He sends mixed signals dating
Your ex is still stuck on you when he dwells on the old memories of you two.When you and your ex talk, he often hits on topics that will allow him to tie lose ends.Maybe he talks about the mistakes he’s made and he talks about how things could have been and ended differently.Compare also Last Het Romance, where the incompatibility causes a character to discover they're gay and break off the relationship. If a character informs someone about an Incompatible Orientation, it's either Sorry, I'm Gay or Dude, She's a Lesbian.
Breaking up is never an enjoyable experience, and in the end both sides are left hurt and probably even a little frustrated.
We all know that the truth tends to come out when we’ve had a little too much to drink.
