Sorry you're here and I completely relate to your 3 terrible unattractive options.
I would take comfort in the fact that you once had a great sex life in your R. Somehow that makes it seem an attainable goal again, but maybe that's just me looking at greener grass beyond the fence.
I highly recommend PM. It has made no difference in my M except in me. That, however, is worth everything. It's helped me be stronger in every way, including my resistance to cheat.
You'll continue to find good advice here and a lot of foolishness, too. (I'm in charge of the foolish part, others give the good advice.) You'll find sexual attitudes expressed by many women here that you'll wish your W shared. (That part makes me crazy!)
Good luck! I truly hope you find the way back to the kind of M that you once had and still need.
