Never try to get involved with a guy who is recently single or has history with his ex.
You’re never going to win him over, no matter how authentic it seems.
The minute she comes back into the picture, he’s gone. No explanation, no note no sign that he was ever there to begin with.
I don’t blame the exes. Hell, I’d want someone to drop everything for me too. Just know, as an outsider, it’s not your place and no matter what you do, you’ll never win.
