Should I remove my ex’s mom from instagram??

I‘m aware how rude this might come off which is why I’m asking input first.

So the break up with my ex was overwhelming to say the least, as he would harass me continuously, I eventually had to block and unfriend him on every platform and his number. I don’t even like talking about him at all, it just brings up feelings I no longer want to feel or think about really. I’m finally in a really good place or at least getting there!

The other day I noticed his mom still follows me on instagram. Which is kind of surprising to me because I know my ex was more than likely bashing my name left and right to her so I kind of figured she would just unfollow me, and it’s been well over or just about 6 months since we broke up too. During the time of the relationship, I was never really close to her. She always gave me the impression she didn’t really like me, she was never rude or anything but I just had that gut feeling and usually my intuition is pretty spot on. Due to that I just never bonded with her and honestly would usually only do small talk with her because that’s all I ever felt comfortable enough to do.

Anyways, brings me to my question is it rude to remove her as a follower or not? Or am I just making a big deal out of nothing?

I know she had nothing to do with the break up and I have no hard feelings toward her. All I really want is a fresh start, no reminders of that time period but a part of me feels so rude/childish to act like this...

Also sorry if this is not the right group to post this under, I’m not sure which category this best suits
