ADVICE

So lately my boyfriend has been a little distant, besides the fact he's on vacation and I haven't seen him in a week. All the habits he does when something's up stop, I wanted to leave him be because he with family. But he's all over social media like pictures snapchatting, he's clearly on his phone and I know he's ignoring me at this point. I don't want to assume but I just feel like something's up, I really don't want to believe it. We've been together for four months now and I'm his second real relationship. I'm just scared maybe I'm not doing enough or I'm not enough in general.
