Is this a healthy relationship?

well I have been in a relationship for almost a year now but we went on a “break” for a few months. during that time he had oral sex with two of my friends, they provoked it. he is a sex addict and is getting help. he also masterbates a lot to internet p@rn which is part of his addiction but it bothers me a lot. I am not talking a couple times a week, like 3 or 4 times a day, and sex! we are in our mid twenties. so anyways we got back together, he says he fell in love with me after those girls because he realized how important I was. I am no longer friends with those girls because they lied to me to my face about this. we met in AA, which I am no longer a part of but he is, so there was going to be baggage from the start. so do you think this is a healthy relationship? we are in love, he is a great companion, we have a great time together, laugh constantly.

also… he plays a little rough, I mean he is a little guy, a little smaller then me so he cant and wouldnt really hurt me. but he doesnt this thing he calls spider bites which are the pinches that really hurt and leave bruises and bites hard(not during sex haha) and some times it does hurt! my friends say its not okkay to leave bruises but its not like he beats me! I pinch him and stuff too.

wow this probably sounds stupid but it is very serious.
