I hear ya. The end of a relationship is a lot like a death and even if it wasn't good for us it is still a loss and it hurts a lot.
I went to a few meeting where everyone had left their S/O and I had not yet and they kind of blew me off. The ones who stayed with them embraced me though and now they are kinda blowing me off.
Now I am in the middle of my family getting clean and it is no bed of roses either mostly thorns am waiting for it to get good one day....
