So my bf (FP) and I started working together awhile ago, everything was fine, felt okay with him around female coworkers except for one. 

While she is pretty, and he’s said before they have similar interests, i’m not exactly sure why she specifically worries me as we work with lots of other girls, and he rarely mentions her. (which i’ve somehow convinced myself means he’s intentionally doing that). She’s friendly to him and he’s friendly back. it makes me feel sick to my stomach and want to throw up, or even start crying. 

Everyone knows we’re dating, and i know deep down my bf is loyal, but i keep having intrusive thoughts of him cheating on me with her. If they are paired up to work together i have full on panic attacks and have to excuse myself to the bathroom or hide that it bothers me. I get so angry, anxious, and sad if i even see them look at each other or standing near each other. I am extremely paranoid that he secretly has a crush on her or she’s trying to steal him from me. I don’t even want him to THINK she’s attractive. Even though nothing has happened, they don’t even talk outside of work. 

I understand this is bad and i’m just extremely anxious and paranoid. I haven’t mentioned this to him because nothing has even happened and I know he’ll think i’m crazy. 

How do i get over this? Has anyone else experienced this before? I know extreme jealousy is a bpd thing, but i haven’t seen anyone talk about a specific person who triggers it. I feel so hurt, and guilty.
