When is it time to walk away?

Hi Faith,
Hope isn't my real name, but I do love the name, and yours. Very pretty.

H truly believes that he is destined to be unhappy, so he seeks happiness from anything external.

Our H's are the same here. I've heard mine say it so many times, how life is so unfair to him, how he's been dealt such a terrible hand (hogwash) and the unhappiness. And he also seeks to be happy externally. He had become so addicted to his affair that it was like watching someone on drugs. It scared me and made me feel I had really lost him for good.
I have a book suggestion for you: Depression Fallout. It's by Anne Sheffield. I think you should read it; it helped me a lot, and I think you could relate to it.

I started needing him to love me instead of just sharing my love with him.

I did the same thing. I realize now that it was wrong of me. It won't happen again, whether it be with H. or someone else someday. We have to remain whole, remain strong in a R. or else we allow cracks in the foundation that eventually break it down completely. Not that we are to blame for what our H's did, but this allows us to see where we need to change.
I don't know if your H. is going to be able to be strong enough to handle a marriage with you again. That is something only he can decide. If you still aren't sure, I'd err on the side of caution and keep DB'ing until you truly feel 100% ready to let go of your marriage. For me, I'm trying to do that so I never have a reason to regret anything I did during this hellish episode of my life.
I do wish you all the best. Take care!
