My "casual", "no strings" lover of 1 year has confirmed that he is "dating&

ms.biz

Well I thought I could "handle it", but it's bothering me. When he told me, (because he was bringing a girl to an event he knew I'd attend) he had a date. I just got out of bed, got dressed and said I had a lot of homework to do. We hugged, he left. Have not spoken since (1 week). No big deal, ball is in my court I suppose.

THE INTERNAL QUESTIONS:
will I be compared?
why am I so hurt?
Should I drop him and WAIT for a guy who wants to be monogamous with me?
(the big one) Is this dude just screwing me while he activly IS searching for a REAL relationship?

THE FACTS:
I knew from the start that he did not want "anything serious"
I thought I didn't either but liked having my needs met
I have never had an on-going "casual" lover before him
we spend time together (which usually includes dinner/movie/sex) once per week
Recently, (about the last 2 months) I FELT/THOUGHT we had gotten close. ie, lots more affection, extended visits (2 days/nights)
I have not had a desire to see others

WHERE YOU ALL CAN HOPEFULLY HELP:
While I'm telling myself to end it with him because, quite honestly, I'm jelous and don't want to torture myself; There is a part of me that wants to "hang in there" because time may prove something worthwhile. ALSO, jelousy has been a life-long thorn in my side and has ended my past relationships, therefore, I wonder if this would'nt be a chance to overcome it. BUT SERIOUSLY.......AM I JUST BEING USED/DUMB/TOO SELF-SACRIFICING
Has anyone had a simular experience? How did you handle it?????
