Isadora,
I was in a 4 year relationship with a man just like that...no matter what I did I was "messin around" or "didn't support him" etc. Well I lost the most important thing while trying to please him. I lost my self esteem, my pride, and my self respect. Not every relationship is the same so please don't think that I am preaching or making less of your situation. I found out that he was cheating on me and got the other girl pregnant and the scary thing was that the pregnancy was what hurt the most because I never did get pregnant. Anyways, I came to the conclusion that I was not so much in love with him as I thought. I was more afraid to be without him and I am better off....I hope beyond hope that you find what works for you and this guy really sees the pain that your heart is in because ONE person cannot make a relationship work on their own.

So now that we all know how long winded I am....good luck and try to remember that sometimes you need to put your needs before others...don't alienate yourself from your friends and family and try to talk to him and see if he would consider going to counseling....again good luck sweetie
