NO, my dear very hasty decision. please don't let jealousy rear its ugly head. Talk about it. because you saw the girl coming out does not mean they're having an affair. if you really love and trust him you should know you have nothing to be fear. I'm sure he would not have invested so much into. you by having you there with him at his home and also knowing you'll be home any second if he was unfaithful. Hès a man of integrity/values. Let love flow unconditionally. in time love will heal/reveal just believe.
