Advice

My boyfriend of 6 months broke up with me 3 months ago (coincidentally beginning of summer) broke my heart randomly, took another girl to homecoming last week, and randomly hit me up 2 nights ago. He came to me so kindly and nice and just broke open and told me how he missed me as friends or as more then that. I asked if he still thinks about us and he says yes. We hung out last night and it felt like we never broke up. He hurt me, my friends don’t like him, and we had a decent relationship but it was mostly one sided on my part. What would you do?
