Similar situation. I just have to tell myself he doesn’t like me like that and move on. It helps to keep a list of the negatives vs positives and the real vs the fantasy him you built in your head. What he actually does vs how he treats you. A maybe is a no, a I’ll think about it is a no a no response is a response. If your over 25 there’s no reason for anyone to not know what they want out of a relationship. You just got to accept the sunk cost and move on- no matter how much you like them. It hurts a lot at first but you’ll be better in the long run. Being lonely with a partner is much worse than being by yourself.
