Should you remain friends during a separation?

[A]

Fiancé wanted a break, he is under immense stress and is depressed, and we had an argument. Instead of letting me be there and try to help, he decided he wanted a break. For 2-3 months. For the first few weeks he ignored every attempt I made at communication, then he finally called. He started calling everyday. But we haven't seen each other and he only calls or texts at his convenience. He will take hours to respond to me. It really hurts me because I got my hopes up that his calls were good and he says he loves me, but he won't text he loves me and when started taking hour to reply I've realized he's just like keeping me here when it's convenient for him. He didnt call me at all on Christmas or even say merry Christmas. Although he commented all over to others online. He has me removed from all his social media as well. I don't know what to do, if I cut off communication it will likely be over for good because he will get angry if I don't reply, but it's killing me just being somewhat friends when he wants and him deleting me on everything. What should I do?
