OK I'm in huge trouble and I really need some help.. well a couple of months ago me and my guy friend had like a thing for each other but I really don't know cause one time we kissed but we decided to never do it again and agree to just be friends.. so one day me and my other two guy friends were in my house watching movies and my sister wanted to go to sleep so she went and my guy friend followed her without me even noticing and when I was going go the room I found them "together" nothing inappropriate but they were "together" (if you know what I mean?).. so anyway I got really mad at him about it cause I really wouldn't care if it was with another girl but I really think that it was wrong for him to go with my sister so I started to ignore him and I really thought that if he really cared about me he would have at liest ask me what was wrong.. but he didn't.. and I really miss him right now we use to have a lot of fun time together and I'm planning of talking to him but I don't know if it's the right thing after what he did? Should I let it be or do something about it? Did I over reacted?. PLZ HELP ME I NEED ANSWERES:/
