Hopeful-

I agree with Jasmine-3 and with your decision. I cannot imagine how upset you were and how difficult it must have been to get that news and to hear those words from her. My ex-wife did not cheat but I was totally lost when she asked for a divorce. I did see a therapist and it helped. You have been through a lot and need to move ahead now.
If you can swing it, move to a new location and sell, donate or split up the stuff that reminds you of her and the bad experiences. I did this when I got divorced. The lemonade is you can set up your own place and enjoy doing it while you process it all. If you pick a new neighborhood you will meet new people.
Good suggestion by the way from tree of life to change you id. It is better to be positive for you. Mine is big blue because I’m tall and I have blue eyes.
