I don't know what to do

I am in a relationship of 3 years, hes has kinda become controlling though and i am always the one to cuddle and do everthing he should be doing to me. Recently we got in a big fight, and i went out with some friends i dont ever hang with.they are guys and their cool to hang with.One of them though has shown intrest in me and treats me great. This perticular guy has a reputation of a playboy you could say. Even though i know his backround and i have a bf i find myself falling for him, he makes my heart flutter. Ive been trying to leave my current bf but he wont let me even though hes cheated a lot in the relationship. I find myself really falling for this friend though he cuddles me, talks to me, and pays attention to me and doesnt expect more. Idont know what to do im in a loop and cant find my way out. Any advice.

You're heading into trouble if you continue to flirt with the other guy. If you're not happy in your current relationship, then take control of it and talk it through with your BF or end it yourself. Plenty of people have learned the hard way that the grass is never greener on the other side.
