So one of my exs has been texting me for about two weeks now. When we broke up it was not on good terms at all. Now he has a girlfriend and a 3 month old little boy. Apparently him and his girlfriend has been having a lot of issues and he has been staying at his parents instead at home with her. He keeps telling me how he is sorry for the way he was when we dated and that he misses me. I don't know his girlfriend personally but from what I do know she is a real bitch, but I still feel kinda bad in a way since he's telling me all this stuff. I do miss him and miss being around him. We did literally everything together and was the best of friends before we dated. In a way I want to stop talking to him since technically he still has a girlfriend but then again I wanna keep talking to him. 😔
