That is a lot of stress to manage. Moving with animals in an unexpected time frame is so difficult. I'm glad it sounds like you and the critters are in a safe place now.
That said...I mean this in the nicest way. You need help. Please consult a therapist or at least seek the help of friends or family if available.
I know it's only been 3 months, but it's time to really stop and think of what can be done to help you move on. If she does not want to be contacted, making posts about the breakup with info like above can cause more issues if mutual friends begin to question her.
I know I've vented about personal matters here before regarding my health and my animals, but for a relationship... This isn't the best place. Leaving it as 'things have been tough for me, I've separated from my wife' is fine. But there is a lot of resentment directed as well.
I hope you both have time to heal from things.
It took a long while to heal after I had broken from my relationship of 15 years. The little critters are sometimes what help the most so do be sure to give them some extra attention from time to time.
I do hope things continue to improve for you if you let them! I do understand the need to reach out. But do also be careful about how you do.
