TITLE: Is it worth for me (26M) to forgive my husband (35m)?
POST: Well...this is a quite long post, I didn't see anywhere that I couldn't X-POST, so, my story can be read [here] (X-POST from relationships).

He told me it was all online, he never actually met anyone, and he's trying to get back with me since this happened, everyday, all day. I'm not sure if I believe him or not, since my trust was completely broken, and I think everything he tells me is a lie. My heart aches so much and I can't stop thinking about our marriage. I really love him, and that's why I'm thinking about trying again, but I'm not sure how is it even possible.

Could you guys help me, please? Is it worth forgiving? Is it really possible to rebuild trust? If so, how?
TL;DR: 
Lost trust in my husband, says he loves me and is desperate to be with me, but I'm not sure if it's worth forgiving.
