Breakups & Divorce Support Group
Just broke up with someone or in the midst of a difficult divorce? Breaking up is difficult no matter what the circumstances are. They say that time heals all wounds, but sometimes a listening ear or a hug can work wonders for the heart. Whether you need a place to vent, someone to hold you to No Contact, or need advice about what to do, we're here to help.

For one, it sounds like a restraining order is something you should strongly consider. Next, thoroughly document all he is saying to you and doing to you. You may need that in the future as this moves to legal papers and court dates.
Getting over the awful feeling does take some work and some time, but it will happen. I'd suggest individual therapy for you, it can be very helpful. Also, it's a paradox and some of it is breaking the chains in your mind. He is going to do all he can to try to make you feel like you are horrible and awful, that's part of the abuser's pattern to keep the victim under their control. Know that you are not awful, you don't deserve this, and you've put up with it long enough. I'd strongly suggest No Contact as much as possible. If you have kids, then only discuss matter-of-fact, absolute necessary topics. Don't respond to any of his other nonsense. If you dont have kids, then there really isn't any reason you need to have contact with him, he can relay legal information through the lawyers. Block his number, change yours if necessary, Block email, social media, etc. Because an abuser is going to pull out all stops to try to get any reaction. Sometimes it will be hateful and/or violent outbursts, other times he will likely try to appeal to your sympathies, heck mine even literally got down on his knees and begged (after lashing out at me failed to work). It's best for your sanity and healing to just cut it off.
You are right: you deserve happiness. Repeat that to yourself a million times a day if necessary.
Big hugs to you.

Find your inner strength and peace. Stay strong.
I can relate to the feeling and have also tried to make a break and chickened out many times over the past 20 years in my relationship.
I'm finally making the break for real and this time I feel different about it. Many things led up to this, but the best/final tool I encountered was finding the book In Sheeps Clothing by Dr George Simon (I was led to this indirectly by a recommendation from another member in the Codependency discussion group).
In a nutshell, I too am over-conscientious (& very avoidant of doing anything which would make me feel guilt). Dr Simon explains how a manipulative (often abusive) person recognizes this in their partner and takes advantage of it. He very plainly spells out more than a dozen covert aggressive tricks they play on you (guilt-tripping included). During the next 2 weeks after reading about this, I noticed dozens of times when my husband used these tricks on me (both during arguments & daily life).
Seeing this in a new light allowed me to 'detach ' (as Melody Beatie recommends in Codependent no More).
Maybe you can find a new perspective with which to view your situation and you'll experience new & different feelings (like being proud of yourself for ending something that's probably toxic for both you and your partner).
Hugs & best wishes to you in your journey.
