advice? im so insecure and depressed I deleted my boyfriend off my social media

W
So my boyfriend is at college an hour away now and we would talk everyday and FaceTime every night and last weekend he was in town but i couldn't see him. He was mad but we made up and couldn't stop smiling from how happy he makes me. He asked me if I can drive down to his college for the weekend and I said I'll try but I was gonna surprise him and go there yesturday. I should add that he has all my passwords but I changed them Bc He was responding to guys I know and friends with telling them stuff. I didn't tell him about that. We would talk but starting Tuesday we only talked through snapchat and then next day only one snap would be sent to me from him. I was getting mad so I stopped responding because he wouldn't respond to me. Yesturday I asked him why he's mad in text and he said he is at practice but he will call me after. He didn't call me only sending a snap video of him and his friends that night. He does not even use his ig, last time he even posted something was 2 years ago and since the summer he's been signed into my ig(he's over protective even responding to my dms) but I checked his account and this girl who I have never seen before commented "how can I even see how you look like when you last posted 2 years ago?" 3 days ago. I went on her page and he follows her. I'm so mad that I went and unfriended him on snapchat so when he send me something else stupid it will tell him he's not my friend anymore. Am I over reacting? Please tell me straight up what you think about this.
