Did he use me ?? or not?

I have a friend that i was fwb with for awhile, he had a g/f and I had a b/f. He kept telling me he would break up with his g/f for me if I would straighten up for him but I seen no point in it because I felt like he was doing the same things as me but wanting me to quit whenever I never asked him too. Any way I kept telling him that it would be a mistake if he broke up with her because she was everything I was not. But since then I`ve been really missing him?? what do you think?
