For context:
This girl has messaged him multiple times knowing that he's in a relationship with flirty messages, and we've even accidentally run into her in public and she will try and make moves on him while ignoring me.
My boyfriend and I fought about how this was disrespectful to me, as in the past he would be friendly back to her and would respond to her messages which encouraged her. Once I brought up how unacceptable the situation was in a fight, he unfollowed her.
A year later, I've recently realized that he's re-followed her, which I find disrespectful as I don't know why he would need to do that as they have no mutual friends or anything. She has followed him this whole time.
Am I overthinking or do you think this is suspicious?
Thanks in advance
