<human>: * Dating 8 months after meeting online.
* We lived close when we first met, but I have since moved about 2 hours away. We only travel to see each other via train. We see each other approx. 4 days out of each month.
* We're gay, he's completely out of the closet and very obviously gay. I am not out at all other than with my immediate family. 

I'm not really developing any new romantic feelings for him since our relationship began, but he appears to be head-over-heels in love with me. We argue all the time, over the phone. I've tried to be as blunt and non-coddling as possible with him when the topic of breaking up with him occurs. 

I've literally told him in exact words that I don't love him, I don't miss him when he's not around, and I don't think our relationship has any longevity in it. Yet, whenever I tell him I think that its over, he starts hysterically crying and moaning, is barely able to speak, and begs me not to leave him. We've had this convo and subsequent breakdown 3 times now and on this last time a couple days ago he collapsed in a loudly crying heap on his kitchen floor, I had to literally cover his mouth with my hand to stop him from waking everyone in his family at 2am. 

I don't know what to do, I don't know why he's doing this? Why does he want to be in a relationship with someone who clearly isn't capable of meeting his needs for romance and affection? I just can't bring myself to just cut him off altogether, I don't know what he might due to himself, or just how vindictive he might be (i.e outing me as gay publicly).

Provide a brief overview of the text.
