Please do not feel guilty for your husband's poor behavior. That is on him. He was most definitely abusive towards you. Laying a hand on a woman, or vice versa, is NEVER OK. Please understand this. He should not have pinned you down on the bed like that. I just wonder whether he may be abusive in other ways, but you take it upon yourself to feel bad yourself and like it's your own fault, when he is at fault and being abusive. Or perhaps it's much more subtle.... but someone doesn't just suddenly become abusive physically without emotional/verbal/psychological abuse preceding it. He also seems pretty selfish, in this instance at least about the stag party.
