The ex decided to sit in front of us, and my gf kept looking at her. She pretty much seems to stalk her because everytime I'm not around she sees her ex, today was the 1st time the ex was around when I was. Somehow she knew she was in a relationship

They've were together for so long and and her ex isn't over her because she kept getting up and walking around while right in front of us. When I haven't been there she will just walk past my gf repeatedly basically stalking her. She texted her ex when she found out that her grandma died, just can't tell if shes over her or not.

How do you know someone is definitely over their ex
