So my and my gf broke up on Monday I told my  friend because I was upset now we broke up over something stupid and Monday we got back together so I also tell my friend and her response was oh I don't see that lasting long.., and I need to be single for a while. Now I was single for 9 months before I met my gf but I feel my friend doesn't have room to talk her gf is in jail for fraud and violation of probation shes dating a criminal basically
