What do you think she could possibly be missing? You said it yourself she got 'cold' .. The cold hard truth is .. She is not 'in love' with you, therefore she is not missing you. Time to step back and look at the big picture .. She's already over you, and has moved on. So should you.
Dated for 3yrs & lived together. Ex moved out but came over a lot Ex lied to friends re the break up details. After 3mo ex got cold Kicked me out & moved in new GF she dated for only 3wk Ex is smoking, drinks more etc since our break up Is ex missing me?
Ex is too unstable
Walk away from this. It sounds like an episode of Jerry Springer. He's your ex for a reason. Why would you go back to someone that doesn't treat you well?
