I'm 5 months pregnant with my son and my ex and I also have a daughter and he has a 7 year old son from a previous relationship, his son lives with my exes mother. Anyway, 3 months ago roughly he left me for a 17 year old, he's 8 years older! It was totally unexpected we planned this baby, and I'm broken. They seem so happy together except now they live with his mother and both now unemployed. Is there a chance he will come back? He wants to be part of our sons life but since him and the gf started living together a month ago he makes no contact with me. His gf constantly brags about their happiness on FB and it brings me down. I don't look anymore and have blocked them. Has anyone else had a boyfriend that came back?
