You weren't satisfied by the fact that you pressured her into giving you sexual favors because she wasn't acting thrilled enough while doing it??? seriously?
You cheated on her and then insult her intelligence for not dealing with it the way you think she should? You have proven to her that you are untrustworthy and no matter how many diapers you change, lunches you bring or presents you buy - the fact remains that you are pretty damn emotionally abusive. I wouldn't be waiting at the door to shower you with attention either.
