Just need advice

This guy and I have been off and on for the last year. Both of us have made a lot of mistakes and said a lot of terrible things to one another. We've both tried seeing other people and it hasn't come close to working for either of us. We always just go back to each other. All of my friends are telling me no, and that I shouldn't be talkin to him again. But it's just so normal to me. And it makes me happier than I've felt in a long time. So I just don't know what to do? Listen to my feelings? Or follow what my friends are saying, because they're just trying to protect me right?
