I just feel so isolated and upset and hurt afterwards I want to resolve it and stop fighting. So we make up. And he's happy again.
This is literally the cycle of abuse.
You do something that challenges his power/control, he punishes you, you submit to try and get him to stop hurting you, he rewards you until the next time you challenge his power...
In the nicest way possible there is almost no point in you writing all this out or in reading it because you are just saying and doing the same thing over and over again, going around and around in a circle.
"He is abusing me. I wish it would stop. I just want him to love me. He says it's my fault so it must be. I am trying to be more obedient so that he will love me."
I think, if you were honest with yourself, all of the rumination and discussions all boil down to these two points from your post:
- I so desperately wanted him to be with me and to fight for us by communicating and reassuring me.
- I have no idea how I'd break up. I'd really struggle
You're not writing these posts or initiating these talks with him because there is anything here that can be salvaged or fixed - or that is worth saving. You are doing it because you want the reality to magically disappear and be replaced with a non-abusive partner who loves you, and you don't know how to exit the relationship.
"If I keep giving him chances eventually he will become the partner I wish I had."
So, firstly, you have to accept within yourself that this is not a loving partner, this is not a healthy loving relationship, and no matter what you do that will never change. If you are only doing things to try and get him to transform into something else, you are wasting your time.
Writing out endless analysis of the same thing is not going to give you the magic powers to transform him into what you wish this was. Pouring your energy into that keeps you stuck because it means you don't have the energy for the things you need to be doing.
Secondly, if having support with you to exit this relationship is what enables you to take that step, then that's what you do. If you trust your mum, would she be with you? It will be painful however you do it - there is no magical perfect way where it won't hurt. But critically that pain will be short term not forever. Staying in this is permanent long term pain.
Digging in and staying stuck to try and avoid short term discomfort will damage you. It is not wise.
Instead of continuing to analyse and debate the immovable reality that he is abusive and this relationship is toxic, focus your efforts and the support you seek on exiting it and rebuilding afterwards. Formulating a plan and some kind of goal or vision for the future after him will give you strength and hope.
Once you take control of doing that you will start to feel better. A large part of what is fuelling your fear and distress right now is coming from the absence of control - you can change that, but you have to do so deliberately.
It is your choice and you have the power to decide to exit this relationship. My post is not written from the perspective of frustration with you - this is your life not mine and these are not my choices to make - but simply out of a desire to help you find the tools and strength you need to take back control of your life so you can be happy and healthy.
