I'm so new at this. But I can tell you, for me, I somehow "just knew" last night. It wasn't a eureka moment, more like a slight tipping of the scales from wanting to save the M to wanting to save myself.
I'm a very analytical person and I've been searching for the formula for weeks. I never found it. I love my W and I would love to reconcile, but for now I'm OK with ending it. Nobody here will fault you for staying as long as you need to. But you are responsible for your own happiness.
I just told this to someone else, but something that helped me a lot is focusing on one goal for now. Not everything. If I tried to solve the whole sitch right now, I'd never be able to get out of bed. I don't have to. Nor do you. One goal. I'd say consult an attorney but it is up to you.
We are here for you and no matter what you do you'll get no judgement here.
Good luck.
