Ladies, I’m embarrassed and I need a pep talk.

I met a guy in July and we’ve been seeing each other since then. He was extremely straightforward about wanting a relationship. He expressed his interest to me and deleted the dating app we met on. We saw each other around 3 times a week and talked every day (mistake 1). I was seeing other guys but this guy and I just clicked. I was able to completely be myself around him. And he paid for everything, took me wherever I wanted, took me to ran errands. We didn’t have sex, he made it clear that sex is reserved for relationships only for him. Fast forward to yesterday, he texts me out of the blue and we’re incompatible and that he doesn’t see a long term relationship with me. I’m absolutely heartbroken. My ego is severely bruised. I don’t understand how we’re incompatible when he’s been saying that we’re so compatible for the past month.

I understand that we need a HVM, but what if you just click with someone?
