Whats is everyones take on this? Since May I have been seeing my ex boyfriend for sole purpose of sex.
The only problem is I'm still in love with him. He tells me loves me and calls me sweet names. He does not want a serious relationship since we are both busy college students...I don't know what to do anymore, should I stop seeing him? I would really love it if our relationship were more than sex but at the sametime I would rather see him (even if it's just for that) than not to see him at all....but don't get me wrong the sex is great.
Also there are other women interested in him...granted I am not his gf but do I have the right to ask if he seeing any of them, or is it none of my business?


You're being used. Think about it - he tells you exactly what you want to hear, he gets the sex he wants, and he can have other women on the side.
If he's telling her he still loves her and all that load, he's playing off of her emotions. If he "loved" her he would have tried harder to find a way to spend time with her. Being too busy is not really an excuse for a breakup. You can work through it. The fact he's branching out to other women implies he has interest in little more than her body.
You have the right to ask him if he's got multiple sex partners. Your health may be at stake, so his sexual activity is your business.
I don't know if it can be considered "being used" if you are enjoying it and satisfied with the arrangement... apparently you are not dis-satisfied to the point of changing anything.
The one thing you might not be acknowledging is that you probably are effectively keeping yourself out of circulation and missing opportunities to meet and be with someone who wants more than sex.
You can make your own decisions, just understand what the consequences are!
While in med school I lived with a classmate. It was a matter of convenience, finances and sex. No more. We did develop a good healthy respect for one another but nothing to base a life together upon. We are still casual friends. It was a two year "booty call" and it worked. We did agree to sexual exclusivity. I cheated once.
Given what you describe, you may be at risk and whether he is seeing others is your business. No details required.
