Two years after breaking up, I deleted my ex who lived together before, and basically looked at my space every day for several months. Does his ex-girlfriend often talk about me with him?

It's been two years since we broke up, and it was deleted long ago. We used to live together, and the former and present came to your space every day for several months. Does your ex-girlfriend often talk about you with him? I often don't know, but I must have mentioned you. You made him feel threatened. Or he is a very sensitive and suspicious person, so he will come to see your space every day. This is a typical sense of insecurity. If you have done nothing wrong, don't worry about him.
