rant/vent

So I think my boyfriend/fiancé is cheating on me. For the last month we've had a long distance relationship 2 hours drive when the traffic is bad. He's a farmer in the "country" and I work concerts and events so I have to be in the city. I do long hours mainly at night and do be too tired to drive to his so stay in my uncles house. I went up to his for Father's Day weekend and it just felt off. We txt talk and snspchat each other all day. But today he screenshoted me a picture something and in his notifications bat it had to messenger tab. He has always said he didn't have Facebook and he does now. And it wasn't just one bubble there was 3. Since he sent me that picture. I haven't heard from him and I don't know what to think or do.  I am not one to have it out with him over txt or a call. So I know I'll have to go up. I just would like to know what I'll be walking into. I don't want to jump to conclusions but if he is cheating on me that'll be the end of us.
