<human>: So.. for the last 5 years I've been in this situation with a guy, who will be mentioned as A from now on. We've been in a relationship, just friends, FWB, relationship, FWB, just friends and then again FWB (I think that covers all the stages). It's been very complicated emotion wise, but I think we've both been in love with another, and still are on some level.

Three months ago I moved cities. We've been keeping in touch, and when I visited home I did visit him and we did our whole lock-ourselves-in-an-apartment-for-days-and-just-hangout-thing. However, shortly after moving here I met another guy (M24, will be referred to as M), who I quickly became friends with, and we've agreed there's more than friendship between us. And I want to give it a shot.

I won't be going home for another month or two though, so I'm wondering what to do about A. I feel like with the amount of history we have, I owe him at least some sort of explanation, and M definitely wants me to put a final end to it.

How should I do this? Do I wait until I go home, to give him a face to face explanation? Do I text him or call him? And - M has said he would be "fine" with us staying friends/in touch, because, well, A has been my best friend through a lot of rough times. I suspect he's not as fine as he pretends to be. Sometimes I feel like the easiest thing for me would be to just end the contact with A without mentioning anything, we have almost no ties except texting/calling/emailing from time to time now, but that would probably be a pretty douchy thing to do? Someone please tell me what to do:(

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: long complicated history with M26 coming to an end, new, hopefully not so complicated history starting with M24. How do I handle the transition?
