Unsure what to do. Feeling so lost.

I have been with my partner for 1.5 years now and at the beginning the relationship started with a lot of anxiety - he had recently gotten out of a very long term relationship and i became very self concuous and worrief that she was going to come back and steal my partner away from us.

We currently live in the house they both originally moved into together and spent most of their lives together in and this was hard for me to begin with.

I have had a hard life, tough and abusive upbringing, abusive relationships and because of that at the beginning of our relationship i came with a lot of control, i needed to feel like i had control over something and this really destroyed our entire relationship, he stopped trusting me, he stopped wanting to talk to me, he hid his feeings and i never knew if i was coming or going. It took him 6 months to open up about my control.

Since then i have done everything i can to make his life easier, i started playing games as he loved it, i let up with all of my controlling attributes, i rehomed my dog as she was too much for him, i got a job even though i was not ready as i knew he was worried about money - i have tried to support him in everything that he does and i have tried to make mends for the mistakes i made over a year ago.

He has recently started to become very aggressive with me, snapping at me for tiny things, getting annoyed at me for seemingly nothing, causing arguments and then deflecting the blame back to me to make me.
