I agree with both PDM and Suzzie. He sounds as if he might be very tense about making a mistake and perhaps is trying too hard. He may feel like he could not prove he had been faithful if he were out alone. Perhaps he feels as tense and awkward about the atmosphere also and it shows in his temper. He obviously seems to love you and wants to prove he is trustworthy. It may also be possible that you are conveying a basic mistrust of him that he is picking up on because of his past indiscretions. What appears to be a change in him may only be something that can be cleared up by frank open discussions where you both are able to express those feelings as PDM said with a councelor. Your guy is doing something a lot of guys don't do. He seems to be trying to deserve your trust.
