Dream About Uncomfortable Car Ride With Boyfriend And Flirty Girl

i was hanging out with my boyfriend and his sister at his house and my friend was there but she ended up going home early but me my boyfriend and his sister went to go pick up some girl who was my boyfriends friend and we got into her car for some reason and my boyfriend sat in the passengers seat which made me uncomfortable and it was his friend driving he was in the passengers seat i was in the back and his sister was in the way back with her ex bf who was her boyfriend at the time but my boyfriend and his friend were talking a lot and she was starting to flirt with him a little and then she ended up getting really close to his face at a red light and when they got a little too close i scream "What the fuck do you think youre doing" and she jumped up and shook her head acting like nothing was happening and i started going off on her for thinking that she could just waltz in here and try and make a move on my boyfriend and then we arrived at my boyfriend's house again and his sister told their mom what happened and then her mom smiled at me because she was on my side and his friends name was nora(even though my boyfriend doesnt have a girl best friend irl) and she was sitting on the couch across from me and thought what she did was funny and my boyfriend wasnt doing anything but by time she had to go home she wanted my boyfriend to come with her because he had to get his car from her house and i refused to let them go by themselves because i didnt know if nora would make a move again or if my boyfriend would let her but i woke up before anything could happen
