Should I dump him?

So my boyfriend and I have been dating almost 2 months. We didn’t really talk a whole lot before we got together and after we started dating he pretty much stopped responding to me, and he would just leave me on read half the time. I didn’t think much of it cause I knew he had bad service at his house (thanks AT&T;). But a couple of weeks ago I saw his Snapchat location at this random house, when I asked him who he was with he just said a friend and didn’t answer me when I asked who. A couple of days later I saw where he was tagged in pictures at a birthday party for this girl, she lived at that random house. I asked him about it and he said yeah it was her birthday party and she asked me to go. I hardly ever get to see him ( partially because it’s summer) but I see him only once a week and he acts like there’s nothing wrong with that. Throughout our 2 months I feel like he doesn’t want to see me or spend time with me, he acts like he doesn’t want to be with me. All of my friends are saying I should dump him but one the days that I do get to see him I feel like the luckiest girl. Idk what to do. Help.
