u think so? I had an almost perfect relationship with one of my exes in the past few years, and one day i stopped getting aroused by him, not even to touch me, infact everything he does began to annoy me. Finally we broke up, i still cant figure it out.
You don't say whether up until that point the relationship was sexually satisfying for you. Sometimes it just really isn't and you get tired of bothering. Other wise there is also the fact that sometimes its a subconcious thing that we are unaware of until it is brought to the surface, like someone said, something he said or did. You have 'blocked it out' but it is still there in the back of your mind.
Why are many of us attracted into relationships with someone who is unavailable ? Why when we find out the person is not available do we stay in the relationship(all excuses and rationalizations set aside) ?
