Last night I (28F) was scrolling Instagram and the people you may know section popped up. The first person was a girls Instagram profile and it said she was followed by my boyfriend (33M) of 3 years. I only clicked it because her name sounded familiar. Turns out, she us the coworker he complains about quite a bit. A little backstory, my boyfriend used to work in security and was a security director of a mall. She was an employee he hired who began a relationship with another employee. Long story short, the two dating employees got into some HR trouble right before my boyfriend left the security company. The guy the girl was dating was promoted to my boyfriends former job so he keeps in touch. The guy and girl broke up and the guy is complaining about having to work with her so my boyfriend helps get her a job at the facility he's swing security at part time. He complains about her all the time, she's lazy, she's crazy yadda yadda. Anyways I happened to be on the phone with him when I was scrolling Instagram so I ask him, "is that so and so?". He gets very defensive "why are you going through my followers? Do not follow her! That's so weird, I don't wanna have to explain why you followed her!" First of all I would never and have never follow someone in his life I didn't personally know. I got very upset at his reaction and hung up. It really bothered me how defensive he got. We ended up talking about it over text and his explanation is she followed him so it would have been weird not to follow her back and he didn't mean to get so defensive he was just worried I'd follow her and make it weird. I let it go but it has left me with such a weird feeling. For context the girl is in her early 20s, I'd say very pretty, and has revealing photos on her Instagram (bikini, cleavage, short skirts). And I'm not slut shaming whatever just weird he'd follow someone back that he has said he can't stand over and over again. Am I overreacting?
