ugh, sorry. It's hard. Please know that many, MANY men look at other women and it is meaningless. They are visual. You are high school sweethearts, have built a life together, etc. so looking at pics of other women doesn't sound like a deal breaker to me. Could he be curious? Are you the only person he's ever had sex with? This does not mean he'll act on it most likely. Looking at pics/video is not cheating. (In my opinion). If he is interacting-- chatting, email, etc. that is a different matter entirely. He lied because he knew he was in trouble. He doesn't want to hurt you. He maybe doesn't feel the same as you do about it. Try talking in a more open way to hear what HE has to say about it. good luck hon.
