advice please

So I was in a relationship for 3 years on and off where he controlled me and abused me for so long but I was so stupid to think this was normal as it was my first ever relationship I then left him and didn't look back after everything he had done to me locking me in the house and keeping me away from friends I wasn't allowed a phone too. I'm now with a new partner and have been with him for a little over a year, he's so laid back and lovely nothing like my ex and I'm still not used to it.. it's like I want him to be jealous and control me sometimes, I've been struggling so badly from paranoia as I visited my doctor because I'm so unable to cope withy feelings and thoughts. I now control him and go crazy over small things I feel like I want to be with him every second of the day I cry my eyes out over small things that I shouldn't get mad about. Obviously this is pushing away the man I love and I just want to deal with it but I'm struggling so badly, can anyone please advice on anything that could help me get over this and save my relationship, it's as if he's still hurting me even though he's out of my and has been for a very long time
