Help!!

So i got out of a relationship with a boy I was dating for almost two years (my longest relationship, also his first gf). i lost my virginity to him , but backing this story up 4 years, there was this older guy (by 2 years) who used to flirt with me and told me what kind of things he wanted to do to me but i was still a virgin , and of course when I started my relationship I blocked the older guy. Well now he's back in my life(the older guy) and lets just say we've done a few times now , but I'm starting to have feelings for him and I know he doesn't feel the same way because he's a player and well, he's having sex with other females. What can I do to make him like me back or what can I do OVERALL??
