How do you know if your man thinks about and misses his ex
He'd probably talk about her or compare you to her. If he's not saying or doing anything out of the ordinary, you should let this go. It's just going to make for problems in your relationship.
Talks about her all the time.
if hes still friends with her on facebook or something or just ask him.
Why do women make things complicated? If he doesn't say it, doesn't talk about her 24/7, don't trip. Maybe the question is do you think about and miss your ex? Just a thought.
