What does it mean when he says he misses me?

[Rhonda]

Back up! If he was really missing you, he would've come to see you (if the distance isn't too much) Don't fall for him because he wouldn't be dating someone if he was really into you. When he says miss you he means just that and nothing more. I mean, I miss my cat, but so what? You see? Its not really affection so don't think it is. If he's now single, it means he's bored and is afraid of being alone. Men are manipulative, remember that. If he really, truly proves he is head over heels for you, then proceed. If not, its time for you to move on.
I hope this helps you! Sorry to sound critical!
