these last two weeks have sucked (and im a terrible person so im going to complain to all you on TheO about it)

I have a really close friend who ive talked to all night, every night for a year now. We usually get along pretty well, though usually our conversations are him complaining about his problems and me listening, giving him advice and convincing him that hes not an asshole.

I usually dont mind this. Hes my friend. i love him to death and i want him to be happy. But he has the terrible habbit of flirting and leading me on whenever he gets bored or cant find any other women to hit on. I am aware that he does it for these reasons. but its a bit cruel to me (seeing as ive liked him for several years now.....)

This happened again last week after he broke up with his girlfriend. ( might i say that when he was in the relationship he lost every one of his friends one way or another including all of the girls who had liked him before. I was the only one who remained his friend.) Because id still been his friend and we'd gotten pretty close i allowed myself some hope that "maybe this time..."
yeah, no... within a week hed found 2 other girls to occupy his attention...

Ive dealt with this before, but by this point i was really upset by it, and that night when talking to him he began to complain about how he could choose which of the girls he would go out with this.
Ive never been mean or even slightly bitchy to him before. Ive always been the one to tell him that its okay, or that hes right (even when hes wrong) He doesnt always complain about such shallow things. i know more about who he is than any of those other girls ever will.
but i guess i kinda snapped when he brought it up again. which ie never done before... I guess i sorta started feeling like he was only using me to dump all his problems on, which ill admit he has. but he hasnt always...
but yeah... now hes all upset with me and i am freaking out and need to hurry up and fix this.
to anyone who bothered to read this, thank you for listening to my ranting.
