2 X 4 warning...
I guess it comes down to three choices. Leave, somehow get to forgiveness, or just slog along like I have been doing.
Bullshit.
It sounds like you haven't done much thinking about how to heal so far; you're without hope. I understand that, but there is hope, if you do some work.
Frankly, from what you write, I think you're still in the JFO stage, even though you're 45 years out. So start from the beginning.
I urge you to find the thread in the WS forum called something like 'What Every WS Needs to Know'. Read it, and look for points that resonate with you. It'll help answer your W's question about what she can do to help you heal.
But make no mistake - you heal you; your W can't do that for you.
Look at the JFO threads like 'Good posts for newbies to read', 'Before you say R', the threads on boundaries, etc.
Check out the Healing Library (link is in the yellow box, upper left of SI pages).
Find a copy of NOT "Just Friends" and/or After the Affair.
I suggest you read about the Drama Triangle (karpmandramatriangle.com, for example - citation OKed by mods).
So far, you describe yourself as taking on the Victim role in a Drama Triangle. You'll never get out of your funk unless you get out of the DT.
You'll never get out of your funk without working on yourself. Consider IC - and if you choose not to look for a good IC, you'll know you are where you want to be. If that's so, accept it is your conscious choice. It's a choice you can make, and you can hold your head high.
But there's a lot more to life than you're letting yourself have. Do the work. Survive and thrive.
