I had a dream with my boyfriend and im very confused kinda angry :/?

I was in small room with my brother and many people i dont know in the back of the room. My boyfriend was in the front of the room sitting in a couch with 3 more guys watching tv. My brother was like "so wheres your bf?" (he doesnt like my bf that much) my brother went to the couch and asked him for me and my bf said something like "im gonna give her a phone so she can communicate with me" and then all of the sudden while i was in the back of the room a friend of him (in the dream he was a friend of him but i've never seen him in real life) came from behind and hugged me and started kissing my neck and said "i love you" and things like to leave my bf he doesnt love me and things like these. I remember my bf would always look at the tv... and at the end of the dream i was stood up in a corner looking at him all mad with my arms crossed and i left the room i woke up and i was so mad at him for no reason.... whas does this mean?
