I've been blocked and don't know why.

Me and my boyfriend have not had the easiest past. It's been rocky but we've been fine lately.. saw him last night. We chilled at his house, went to eat, then I went home. Things were great. We were supposed to be hanging out today. Today, I'm blocked from Facebook, all calls go directly to voicemail, and deleted from Snapchat. I'm not blocked from there because I can still see our conversation but I can't add him back. Is there a way to text/call so I can get some answers? I'm so confused..
