I wouldn't say that the relationship is over because he has been peeking at porn. Trust me I know it hurts when the one that you love is getting "his" by porn and not with you. My husband cheated on my a few years back and it was difficult to get over. He is still looking at porn and IMing the girls on the sites. Am I concernd, yes a bit. But it is not enough to say I want to walk away. Like you it is more my insicurities than anything. I know my husband loves me and the main reason he does this is because he works out of state and I only see him a few days a month at best.

Don't end the relationship because of trashy girls. Guys don't bring those girls home to meet the parents and they sure don't marry them. He is with you because he wants to be. It seems as if you feel that he would not cheat physically but the visual is bothering you. Have a good heart to heart about it and work through it.

Best of luck for you and your guy.
