Do you expect people to invite you into your life who don’t want you it just because you took it upon yourself to put unwanted un-asked for effort into trying to hard?
Look buddy, if someone doesn’t like you and does not want you around them, you trying too hard and making the situation worse, making yourself even more ugly, is entirely your fault and problem. They simply don’t like you for one reason or another. Did they say you “try harder to the point of being irritating and maybe I’ll let you in”? Or did you take it upon yourself to be clingy and irritating with the expectation that they will cave and let you in?
It doesn’t sound like they did. Maybe they just don’t like you. I can I defer and that, you are a moron. Sticking around and acting like a clingy psycho crazy is repulsive to anyone. It pushes people away, and they are even less attracted to you than when they dropped you like a bag of s***. You just make the situation worse and yourself and the situation more ugly. The best course of action when someone you still want rejects you is not to cling. It is to s*** it up, and make yourself disappear. If they miss you, IF they miss you, not when, maybe then you have a shot. Maybe not though, that’s not a guarantee.
They just don’t want you. If you try to hard to change it, that’s on you, not them. They didn’t ask for it. You should have been gone.
