Sad life ...

I've had the same sex partner for a few years now at first he was just another guy that satisfied my needs but now tbh I'm madly in love with him. Sadly, I know he sees me as nothing more than just a girl he has sex with. I guess he could since I have no self respect when it comes to him. I let him treat me a certain way & now it sucks that I know he would even act like he didn't know me if we saw each other out in public. It sucks so bad .. Why do I even put up with this ????
