Only you can truly know that. Maybe take some time to not be with anyone for a while. Get to know you before you try to change for someone else.

Perhaps the only thing wrong with you is the type of person you are are picking. If nothing changes, then nothing changes. Make at list of the characteristics these guys have in common. Maybe, just maybe you will find a common thread and know better what you are setting yourself up for.

I agree with both prior replies, and in combination. Taking the time to get comfortable on your own, being alone, and learning who you really are will be vital to understanding that you are fine on your own, and in understanding what you like and don't like. This will help you be whole as an individual, and make you available as a true partner. This will also help you know what to look for in a partner, what is most important to you, and what you are not willing to live with. Being comfortable on your own will make it easier to "pass" on those opportunities that don't meet your criteria.

Go out and buy this book today "I can do it" by Louise hay< it will help you attract only good into your life. It really works, trust me

Some of us are poor pickers of men and women. I tend to choose the ones that suffer from self esteem issues. I've been married twice, my 1st one was a controller and so ornery and moody, I divorced him after 20 years, my 2nd one was an emotionally unavailable man and left me after 7 years of marriage, he broke my heart and the reason I stumbled upon this amazing website. I'm going to be extra careful if I ever think about marrying a third time, I want to be but it's down right scary out there.
I highly suggest this book "How to Avoid Falling in Love with a Jerk" It's a great book. I learned a lot about myself and what to look for next time I get serious in a relationship.
For now, I am taking a break from dating, I love men, love being in a relationship but I need to figure out my life before dragging a man along with me. Hang in there, take your time and keep your eyes opened and watch for those pesty red flags. More importantly, love yourself and be the kind of person you would want to be with. Hugs.

You are not toxic , they are. You are trusting and you may have missed some warning signs along the way ( although sometimes there is no warning) if you notice any then avoid people with those traits. Either way, they did this to you , it reflects on the type of people they are.
