He hurt you and it’s obvious you felt really bad about his action, who wouldn’t? If you really want your intimacy back, you start by forgiving him sincerely from your heart. I don’t know the level of your communication, because he needs to know why you have been acting up. Both of you need to talk. Forgive him, very important. Reply
