I have felt many of the same things you have. It is a hard thing to deal with. My husband has just asked for a seperation and a divorce after six and a half years of marriage because it is now to the point he isn't in love with me anymore. I'm having a really hard time with it which shocked me because I had often thought this relationship wasn't the best for me. A friend of mine kind of hit it on the head. I took my vows seriously and I love being married. To do things for him and make him proud or happy was my way of fulfilling my needs in this relationship but also required me to lose myself, make allowances, and basically do all the work to make the marriage work. I gave and gave, sacrificed so much. It seems to me you are in the same boat in some of those aspects. Its hard but life is about doing things that make you happy, make you complete and fulfill you...even if it means ending your marriage.
