Ive known my best friend for about 5 years now.

Hes always been super kind, but very very clingy.  He's also had a huge crush on me thats always been very obvious. I used to share the feelings 5 years ago, but they died because he got incredibly demanding with me speaking to him everyday, and would freak out if i didnt.

Ive found myself splitting more and more where he's concerned and its becoming harder to hide. Im just sick to death of him. I'm sick of being forced to interact with somebody whose weird obsession with me makes him ill. I cannot spare the emotional energy anymore to even pretend to care when hes upset. Infact most of our conversations just devolve into me repeating over and over how i do not have feelings for him, and im sick of him trying to rule my life.

I've tried explaining to him over and over that he cant expect me to be sociable all the time, and spend every waking moment with him. Since i have other friends and irl commitments. But he still freaks out.

And yet if i told him this, im totally sure he'd do something stupid. I care about his wellbeing.  I just dont care about him as a 3D person anymore.

Does anyone else find this happen?  How do you deal with it. Im getting tired of just exploding with anger every time he does this, and im sick of being called a horrible person because i cant articulate my emotions correctly.
