My ex and I had to split our 2 dogs when we got divorced due to housing situations. Losing one of my dogs was devastating. So yes, I would watch the dog when the 3 of them or even the 2 of them took a trip. He was mine from start. And when they had to put him down last year, my ex called me to come over and say my goodbyes. I cried and held that dog. It was so hard. So I understand where you are coming from.
I do think you borrow lots of unnecessary pain otherwise. From a man who has caused you plenty of pain . Now you can free yourself of the pain, and you still chose not to. I honestly don’t know how someone deals with the abuse you suffered without IC. I think sometimes you don’t know how to live without the pain.
As far as the stuff on your plate..... it can be overwhelming at times, but you take everything one step at a time. Fight the immediate battles first, the other stuff can wait .
