Hey, stay strong, shit like this happens, i was with a girl for over 2 years and got really close with her family. then we broke up, but i feel like soon we will become really close friends again. I think a break is a good idea. you can take some time to find yourself a bit more. He sounds very confused, maybe make some plans with a friend or something. you might end up getting back together with him, but maybe not, and that is ok. endings can suck, but they generally mean the start of something else which will be awesome for you.
Being alone, The opportunity to become strong within yourself, One of the best things that you can do, Make sure sure you take time to be alone.
(If it's hard to be alone with yourself, it will be even harder for someone else to be alone with you)
I hoped something I've said has helped you. Good luck.
