why do you hate yourself? Why don't you hate him?

You're warping your anger around to hurt the person already hurt. Go to the gym and punch something. :)

I hate myself bcuz I always put myself in situations where I get hurt

Exactly! I think you've already made great progress!
You hate YOURSELF for picking him and allowing him to hurt you.
The thing is, you're not ugly. Steve Buscemi is "ugly"... hasn't stopped him, has it?
You're being played for sex because that is what you're picking. You don't have to be good enough for them, you have to be good enough for you, then men will come to you (trust me, I'm a man :D We feel attracted to basically any woman who is certain of herself).
It is going to be very hard work, but you need to get yourself to a position in which you can stand for yourself and not beg for love or sex or affection from anybody. You need to be enough!
Don't let anyone define your worth, and don't bully yourself into thinking you're not enough. You have to be! Make yourself into enough! Fall in love with yourself. Your looks are irrelevant (and I'm sure they're not as "bad" as you're saying anyway, they never are).
Work on yourself and yourself only, not on getting men. Spend a few months with just yourself, but working, making you into the woman you want to be. Learn to talk like you want to talk. Learn to act like you want to act and react like you want to react. Then you won't even need men, but they'll come anyway ;-)

I agree with Visc
You need to be whole as an individual. Love yourself, be ok as yourself. If not, repair yourself, learn what you need to do to make yourself happy. Therapy will help for sure. Having a relationship just to fill a void you have will always end in failure. You'll keep making the same mistakes.

If you repair that void or that need to have someone just to make you whole...you will be better off in your next relationship. You may recognize the red flags in people to avoid the same mistakes.
I wish you well -HUGS-

CODA and alanon meetings help alot too,
for self esteem and self worth issues. If you
came from a dysfunctional/abusive home.

You were not taught as you should have been
as a child to value yourself and love Yourself,
You matter and you are enough, HUGS

You're giving yourself to these guys looking for love, approval and validation.

You feel full of self loathing because YOU have abandoned yourself, not because of them.

You don't need someone else's approval.

You are full of self betrayal.

What can you do to help yourself?

Many of those issues are very deeply seated a good
therapist can Help guide you toward more productive
Ways of thinking and feeling good about yourself.

I am serious about CODA/alanon they do help many
of us that come From unhealthy backgrounds.

You are young keep Reaching out for loving caring
healthy support to build yourself up. Stay out of new
relationships until you can heal, grow and get stronger
From the inside out, to me that is a healthy plan of action,
HUGS

Please know that you are already learning from your mistakes as you are aware of what you are doing. Awareness is huge. I used to seek affection and attention through sex, and felt worthy and relevant if a guy found me attractive enough to sleep with. But when I wanted to see them again and they weren't interested, it hurt. I got to a point I wanted to give up on men altogether. As a last ditch effort, I decided to go for a guy that was opposite of the type I usually went for, someone I normally would have thought of as square...Good job, liked to party but also had more mundane hobbies...And only a few notches on his bedpost. We ended up getting married a few years later. You may not identify with any of this story, but I'd like to leave you with this: try something different than what (or who) you've been choosing to do, try waiting longer before you sleep with him, and keep an eye on his attitude towards women...If he doesn't respect them, he won't respect you. Know that you deserve respect. I had to kiss a lot of frogs before I found my "prince" and by no means has our relationship been perfect, but I feel fortunate to have found him. I understand the urge to cut, and know that it is intense emotional pain that brings you to that point where you need that physical pain as a distraction and release. But I hope something I've said helps you to feel less of the urge to scar yourself. Better things are in store for you.

I'm so sorry you're going through this, bremyselfandill. Heartbreak is tough... it sounds like you may be realizing now that it wasn't the healthiest relationship if he was just using you. You are more valuable than you know and you deserve the best! The best isn't being broken up with over text or being used for sex. Have you considered taking a step back from dating for a bit to reevaluate what you look for in relationships and possibly ways you can avoid this in the future? Is there someone you can reach out to today to let know what's going on and how you're feeling? Cutting won't make it any better, trust me... I know from experience. Sure if may help to get your mind off it in the moment, but in the long run it's only digger yourself down deeper in a bit that's tough to climb out of. Praying for you today! Here if you need to chat. *hugs*

I'm new but please don't call yourself ugly. I know you're in Pain but please don't do that. I have freckles or Moles and my ex boyfriend that Ive known for 39 years told me to "Get them Black Spots cut off B^% <&." So from someone who has just been hurt by name calling, please don't call yourself Ugly. I know it's Corney but a quote from the Bible says, "Man looks on the Outer Appearance but God looks on the Heart."

Regardless if you are ugly or not, dumping someone via text message is a dick move. If it gives you some comfort I am a model (meaning that I should fit this fucking society standards of beauty? and I've been dumped in any possible way (text message included) Don't beat yourself up. I recognize I was an awful person back in the day that could be one of the reasons I got dumped .
Someone told me "beauty opens the door and brains keep you inside the house" Now that I am in my thirties I see what he meant. You will find the right one. Love yourself. Hugs

I wish you didn't. I wish I could be there to tell you guys suck and it's NOT you. Always wanting to bury their stick in a new hole. Seriously. I know it's gotta hurt. But, just don't blame yourself... Coz he IS the ass... breaking up by text??? Where's his integrity? See.... if that's what he's made of... you don't want him anyway... You wouldn't have wanted to live with "that" for the rest of your life... say ba-bye and don't let the door hit you in the ass on the way out" (We need to go have a drink! )
