I(37m) Just got released from prison on a false charge and found mg gf(35f) married with kids

I was in prison regarding 12 years on a false charge. I used to have a gf and I lived with her and we were going to get married someday. Well I got arrested of some shit I’d rather not go into and after 2 years she stopped going to. For 10 whole many years thinking of the day I’d get out and see her again was your only thing keeping myself going. I was released recently and I couldn’t wait to meet her again after so long but found out from my buddy that I’m staying with currently that she had moved on and got married together children.

I’m glad the lady found happiness but I actually can’t describe the pain Personally i think. The one thing that kept me heading, the only source of hope plus my reason for living was gone. I don’t know merely can even start over with relationships at my age since I’ve been locked up for over a decade I wouldn’t understand how to start anything. How can I move ahead from this?
