I imagine that this is very hard for you. You have your dream guy, but you've not seen any of his faults. It's really hard for someone in real life to compete with the fantasy that the two of you have created. It sounds like you're trying to escape the same ole by chatting with Mr. Wonderful.

I think what you have to do is realize that although this guy that you're chatting with online has some wonderful qualities, he also has a list of flaws that you're unfamiliar with.

Three years is a relatively long time in a relationship, you know each other well and there are no surprises. Personally I'd quit talking to the guy you know you'll never have a relationship and take a good hard look at the one you're in. Talk to bf about the things that you dislike in the relationship, ask his opinions on what he'd like to see changed. See if the two of you can't make your relationship better. Good luck!
