I know this is bad, but I'm not sure what to do?! Its like the song "can't get that at home" by blake shelton?

The romance has died between me and my bf of only 9 months. I've tried talking to him about it, asked him if we can do special simple things together like just talkin and having him cuddle me and love me. Not just have s e x that lasts 5 minutes and he leaves me to watch tv. I still love him so much and I know he loves me. he just doesn't show it like he used to, he told me "i have you now, i don't have to keep up with keeping you happy." And he always makes fun of me and is hurtful but laughs. But then this guy from my cl (college not high school) has been letting on he really likes me. for the past month we have been hanging out a lot, we love all the same things. But this past week we have started makin out in the stables. he said he really likes me, but doesn't want to ruin things between me and my bf (this was before we ever kissed) and he said he felt it was wrong and i said i did too. we both feel bad, but there's just something there. we've known each other for awhile now, but never talked bc he had a gf and i have a bf. but his relationship ended going down like mine is now. But he doesn't want me to break up with my bf for him. said he'd feel awful. Its not just the making out i like, its the way he holds me and makes me feel like everything he wants to hold. I've always heard don't leave the one you love for the one you like...but i don't know what to do. I can't talk about anything with my bf for 10 minutes, but 4 or 5 hours will slip away from me and the other guy just talking and enjoying each others company.
