I hate to be a cynic here....but right now I am. I sat in your shoes for 2 + years. I was too patient, I was too forgiving (my C just told me she believes I've been way too patient...I fear you run that same risk). I did EXACTLY what you are talking about....and 2+ years later I've found out my H has been having his needs met all along on the internet.
I heard the SAME things you are hearing from your H from my H. "It's not you, it's me."...."I don't think about sex", "I have to step up or I'm going to lose everything" blah, blah, blah....which changed to "I don't think about it much". Each time he'd do something tiny to appease me and show me he was trying. Sad fact is...he wasn't trying and was doing what it took for him to actually avoid true "intimacy" with me by getting his needs met online.
I really urge you to look deeper into your H's activities. If for no other reason but to avoid doing what I did for 2+ years....only to find out I'd been wasting my time. I now know I'm dealing with a COMPLETELY different problem than what I'd been working on.
It's a very tough thing to delve into these things, it's uncomfortable as he!! to check up on someone you love, someone you believe you can trust. I'm telling you these things out of hind-sight now. Check, make sure he's not doing something else. If nothing else you can come back and say GEL you were wrong....and have that peace of mind.
