I really love him but....

I've known him since highschool. I know I shouldn't be messing around with him. Because he admitted he has other sexual partners. But Ive liked him since highschool. And I wanna be with him. But I'm not sure where he stands. I asked him. He said he liked me too. But I'm feeling as if I'm one of his sexual partners. Ive been used alot in past relationships. The men just wanted to get in my pants and thought my kindness was just me flirting or something. I'm so torn about this. I really do love him. Alot. I honestly see myself with him in the future.

Update ...

I don't know why I'm doing this to myself. I'm suffering because I just wanna feel loved. And have a partner. A serious partner.
