Can I ask her to unfollow her ex?

I'm worried about my girlfriend and her ex. They're interacting a lot on Twitter and even say "I miss you to each other. We don't even do that. I'm just wondering if it's okay with her to unfollow her ex or at least tone things down. I don't want to sound controlling or overreacting but it really bothers me a lot. Although, they only met online in some new profiles love search, I still consider their relationship real. They had feelings for each other once, they could have feelings for each other again.

I get that it makes you uncomfortable, but it might be something she isn't aware of! Maybe you can try and talk to her about how it makes you uneasy and show her where you're coming from. Theres no reason for her to think you're controlling if you just try and explain the situation from your side.

I can understand what's going on in your head.
Trust me,it's completely fine to explain your feelings to your girl.
She is your girl man you have all the rights.
There is no problem,if she is in touch with her ex.however,if they still feel for each other then that's definitely not a good sign for your relationship.
Confront and clear the issue.
Don't worry,be cool and everything will be fixed.😊
