Well I'm glad you are going to a local meet up group and making plans for new living arrangements with family support nearby too. That all sounds positive.
I'm sorry your W is PMing some guy - that tends to happen
I just wanted to comment on the 'negative framing' of things - something to notice in ourselves and watch out for - "I struggle with relationships" "she is not changing her mind" "she will never get back with me"
We are all flawed individuals who struggle with many things and excel at others - that's fine. As for the future, who knows how that may unfold, and how your W may feel in time?
Good luck with your plans
