Fiancé wants a separation?

[A]

After a minor argument he said it was over because he needs space to deal with family issues. He is under a lot of stress with ailing parents. He wants a few MONTHS. I'm devastated of course. It's already been 5 weeks. We have not seen each other, but have talked. Sometimes it's good sometimes it's not. He refuses to discuss us. He gets angry if its mentioned. The only thing he says is that he loves me to death, he hopes it works out, he could never love another like me because he will always love me. But his actions are different. One minute he says he loves me, the next he's treating me like a friend. He has deleted me on all social media, but I can see he is adding a lot of new people from around the world. I know he wants space, but it hurts so much to see him friending and chatting with others while he's ignoring me. On the text app we use I used to see he would check it all the time now he checks it maybe once or twice a day. He rarely initiates any communication. I'm going to back off since he really hurt my feelings again tonight by telling me to get off his ***. All I said was a response to his question. I am hurt and confused. I love him but he is being cold and mean. I decided not to text anymore because I'm obviously no longer his priority so I can't keep making him mine even if it hurts not to. I've never had to have a "break" from anyone...is this normal behavior? He hasn't called in 2 weeks. Or is this behavior because he is so stressed and depressed about his parents?
