So today at lunch my boyfriend and I were eating in your usual spot, chillin, both on our phones a bit. Then, out of the corner of my eye I see him open Snapchat. It’s a snap pic from a girl (you know, the kind where you include part of your face and write whatever instead of just straight up texting.) He sent one back, same format yada yada. I don’t know why, but this automatically made me feel kinda down. So I went back to watching my movie on my phone with an earbud in, and I know this is nosey but kept looking at his phone out of the corner of my eye. They were basically having a whole conversation over the little pictures. He noticed something was wrong I suppose as he kept trying to hold my hand and such but I was kinda like a limp noodle. Not not holding his hand, but not tracing my thumb across his hand and rubbing it as I usually do and as he was doing. I don’t know why I’m so upset about this, it’s not like he was hiding it from me or anything, he opened her snaps with his phone flat on the desk most times. Anyways this just totally left me in a bummer mood in which I’m sure I looked depressed. I don’t want to be that overly jealous girlfriend and I don’t know if I have a right to be upset by this. But I also don’t know who this girl is and I’ve seen that months before this they had been talking with snap pics. Please help?
