Mostly agree with everything Zues said. I see why you want to move forward with your life and not be tied to W the next year. It's going to be an exciting time and you should enjoy the experience. You can still do that. It might be easier to let go and move on but realize, just like other people in our lives that care for us,those men want you to stop suffering. Being M to W is that suffering and the quickest way(so they think) to get past that is to cut the cord. But that may not be your path.
If you don't believe in D then don't D her. Limbo [censored] but maybe it's exactly where you should be right now. I've faced the same thoughts so I understand but out of suffering comes growth and growth can be amazing. Who knows what else you could learn about yourself staying where you are. I'm lonely also and having my needs met would be great, but again, maybe it's not time for a reason.
Accept what is, let go of what was, and have faith in what will be
