Hi sunshine, my DH used to be controlling when we first got together. The stress of me going out alone was overwhelming so I too just gave up arranging anything on my own. He wanted to know and control every detail of my life. It was incredibly stifiling and actually got worse when we moved in together. He too admmitted he was controlling but it did not improve things.
I changed as a person, became quieter, more malleable, much less fiesty (not that I was really fiesty in the first place). The problem was when we were alone and I had nothing planned and I was all 'his', we had an absolute whale of a time and I adored him.
Then... we had an enormous row one day and I left him. Just packed my stuff and walked out. We were due to go to on big hol the next day but I refused to go (despite desperately wanting the holiday and hating the waste of money, but I was SO sure I needed to do this that it gave me the strength of mind not to succomb). I got a flat share ASAP. Over the next six months we talked at length, he admitted loads of stuff, told me why he was controlling etc. etc.
We got back together. That was 4 years ago and I swear to you - it is truly astonishing how he has changed. Totally relaxed with me, totally chilled about me going out. A different man. It is like that big palava shocked him and then the fact that I agreed to give it another shot, showed him I really loved him and he didn't need to be controlling.
Sorry I have gone on at length. I think my point is that it might take a LOT of energy to get to a point where he is relaxed and not controlling.
What you have to ask yourself is... is he worth it?
