belle, don't make any decisions or come to any firm conclusions about the relationship while you are upset. it's best to do that when you're in a stabler place. it may be that just as you are having issues with abandonment he may have issues with sex. he's trying to support you with your issues so i think supporting him if this is an issue, and not just a difference in sex drive, is a good thing.

having said that, i know you are also wondering if he is the one for you long-term. maybe it would be helpful to really think about what your priorities are in a long-term relationship/marriage partner. i remember reading an article years ago that said to list the top 10 most important things to you in a relationship. you only get 10 so you have to prioritize. then you had to determine which were essentials that you had to have and which were things you had some wiggle room on. there may have been a limit on how many essentials you get to choose as well but i forget. of course this is only a good guideline (no rules!) but i found it helpful to really think about what is important.

it's always interesting then to see how what you say you value lines up with the types of guys you choose. it may be that you aren't picking guys with long-term potential or you don't really value what you may think you do on paper. for me i can say i want a good, nice guy but in reality i know i'm going to sacrifice a bit on the niceness for someone with a bit more excitement. not saying that is a good thing but for me i know it's true by the people i've picked so far. i figure i might as well be honest about it.
