Boyfriend Filled Out Profile On Match.com

I have been with my boyfriend for about 21/2 years. He is in the army and was suffering from ptsd pretty bad a year and a half ago.

During this time, he went onto match.com and what started as him looking at the people on there, turned into him filling out a profile.

He did not pay to be a member and never talked to any girls or saved any profiles.

About 5 months ago, I started to really get upset about this and started obsessing about it (at first I didnt know about the profile, only that he went on the sites., eventually found the profile after snooping).

After months of him saying it was nothing but a joke and that he filled the profile out only because the site told him to, he finally admitted that he did it during the real depressed time of our relationship and that he only did it because he was so depressed and self conscious that he wanted to see if anyone would even be interested in him.

He also said that he didnt know why I was with him because he didnt feel he had anything to offer.

He says that his ptsd had a lot to do with it and that if he wasnt struggling with that, he never would have went on those sites.

He said that as time went on, he realized that I really did love him. He swears he never wanted to cheat or talk to the girls that it started out as curiosity and just got out of control.

Since all this, he wants to marry me and is very remorseful for what he did. I, on the other hand, I'm so hurt I cant seem to stop thinking about it.

Do you think that what he did was a betrayal or just a man down in the dumps trying to feel better about himself?

Should he be forgiven or is what he did the same as cheating?

I love him so much and know that he loves me but why cant I get through this? What should I do?

Please help?
