He cheated on you for a year. If there was going to be a discussion about an open marriage that should have happened before he cheated. If you’re thinking about getting back with him, think about all the times your cried on the couch because you wanted to feel loved and to be touched. The guy seems like a piece of garbage and you deserve much, much better. You deserve to be loved by someone that’s is going to give you everything you’ve ever wanted in your life. Get him OUT OF HERE. Good luck OP. I hope everything works out for you in the end
