I think you are extremely wise to be cautious with him. If he is ready to ditch ow, he may test the waters to see if you are ready and waiting for his signal to jump right back in. He probably thinks that is just what can happen.

Wow, that was a dirty thing to do when ow got with another guy, and your H brought his depression over to you, only to whizz right back out when she crooked her skanky finger to him. How can you trust him again after that? You can't. At least not for a long time, with a lot of counseling.

If that is what happens when he gets ow out, you have a lot of thinking to do, and I believe you kind of will have the upper hand; it will be your decision to make, and to take your time doing so. Time really is on YOUR side.
