Nah. It's only women that do that.
To be fair a lot of mofos cant handle it when i woman tells them to kick rocks and start harassing the women. Mofos have no pride

Once im done with someone or they are done with me i keep their number for years if not forever. Never burn bridges. She could be lonely one night and needs some dikk and would rather go with the familiar dikk.
Ive had chicks that i stopped fukking a decade ago that i'd holler at on a lonely night and they'd come through. If you treated a woman well during and after whatever you had with her she'll always have a soft spot for you. Even if she was to be married, she's one bad argument away from coming over and getting backshots on the couch.
