Keep up whatever you can. It is a LONG marathon. Months, maybe years. That's tough to accept, but I'm in the same spot as you. W got contacted by OM on Valentine's Day, and started talking with him again. I think his D is coming to a close, so he needs validation, and the EA starts again. Maybe not, but either way, I can't control it. I made way too many attempts at MR, when I was better off focused on what I can control in my personal life, and be there for the kids. My W's heart issues aren't fixable via any quick fix, and will take months - I'm thinking 6 months minimum - to get to the point where she would be willing to put me first, in front of her, on anything. Until then, the M sits.
Continue to transform into the best version of you that you can be. Honest, trustworthy, kind, calm, smiling, devoted to your kids, courageous, selfless, and hard working.
Your W will figure out what she's missing in due time. If not, her loss.
