He ignores my snapchats sent to him but watches my snapchat story?

I guy I've been kind of seeing the last 3 months has gone home for Christmas since he went over a week ago he hasn't contacted me at all and I usually hear from him everyday (or every other day at least) since he didn't text me I measaged him last week and we were talking for a couple days then he stopped replying all of a sudden. A few days later I text him on facebook saying merry Christmas but he's just ignored it (hes been online but just hasn't opened my message). And now I've saw that he's watched me snapchat story from last night but still hasn't opened the snapchat i sent him last week? I really like this guy and we were really good friends for a bout a month before we started seeing each other. His ex cheated on him before we met and she's been trying to get him back ever since he's told me he would never go back to her but since they both live near each other at his hometown Im kind of scared that something is going to happen between them. I can't see any other reason he could be ignoring me for :(

Should i ask him whats up or just ignore him in hopes he will contact me? We were really good friends first which is why I don't understand why he would just ignore me like that. He was really nervous about going home because his mother and father just split up so I only wanted to. make sure he was doing ok with that.
