Would you keep in touch??

Would you keep in contact with a guy who showed interest first and pursued you, lead you on to think things were going somewhere between you both, showed affection just to pull the plug randomly after making plans after 3 months and then ask/ hope to remain friends? I feel very awkward knowing that I was an “almost” or “could’ve been” girl (I’m 28) to now be in the friend-zone…doesn’t make me feel good about myself or that I wasn’t good enough and to now be put on the sidelines after all of that?? Makes me feel small while he carries on and more than likely with someone else or already had someone else at the same time. Like I didn’t “make the cut” and I replayed EVERYTHING in my head and I know I never said or did anything that would be off putting toward him. Like everything was going fine as far as I could tell, he kept chasing me and I would return the effort. Feels like I got hoodwinked and it’s embarrassing. I don’t date often because of situations like this, feel you can’t excited anymore because something is always bound to happen or just when I think I can let my walls down and feel in the safe zone is when the rug is pulled under me. Dating shouldn’t be this difficult, usually I know after like 4-5 dates I wanna try something with said person…doesn’t take 3 months and going out 1-2x a week consistently to figure that out 😒
