Am I over reacting?

Long distance boyfriend went on a trip with friends ( he has a bunch) & I don’t have any. We are planning on buying a house soon but things are getting a bit hard because there is nothing out there during these times. I just feel a bit lonely because of this distance & wish he was taking thing long weekend to see me instead. But I understand he has his own life and things to do and it’s not all about me. I get a bit insecure and think of all the “what if’s” even though he has proven in every way that he is honest. He has been sending me pictures but I just wish he would call me up and check up on me more. Maybe I’m just being needy. Distance hurts & I hate playing so many mind games in my own head and making assumptions. I just see that when we see one another he answers his friends calls but how come he doesn’t do the same when he’s out with his friends? I mean he does occasionally answer if he can. I just feel I want more attention and it hurts. Any one else go through this?
