I keep getting unreasonably paranoid and suspicious, questioning every single thing my FP/fwb (complicated?) does... 
example: She sent me a picture showing me how her hair is almost reaching her butt and I noticed it was taken 3 days ago. I instantly got paranoid and asked her who else she’s been sending pictures to. She said she took a picture of her hair to show her mom bc she had dyed it a few days ago and her mom asked if she needed any help with it since she’s colorblind. I still didn’t believe her but knew i was being illogical and just went and took a shower and didn’t respond until after my mind calmed down.. 
idk what to do, i don’t want to be controlling but i get so stupidly jealous over nothing. I shouldn’t even care who she sent the picture to in the first place.

tldr; got insanely jealous and paranoid over something that shouldn’t even matter and don’t know how i should handle stuff like this.
