You know, I think you've answered your own question here, and it's to do with you and not him. The fact that you have identified him as immature and an ex suggests to me that you are more than ready to move on, and to go back to him, even if he wanted you back for any other reason than he can't find another girlfriend to replace you, would be a waste of your time and his. So take charge here. Tell him it's over, to stop calling (use your caller ID; that's what it's for) that you have no feelings for him, and you are not going to be his sympathy date. Of course, if he's really immature, there is always the risk that this kind of firm treatment will make you that much more desirable to him, but he'll get over it eventually, unless you give in. Phil
Instead of looking for signs how about you be the bigger person and actually ask.
It depends on the type of person he is really.
An exboyfriend texting you could mean almost anything. It could mean that he just wants to talk, that he wants to get back together with you, that he has something specific that he needs to tell you, etc.
He'll tell you.
If you talk regularly and she says she misses you.
He tells you.
Sounds like she is seeing how far she can go with you. That could be a sign that she don`t know what she wants also. sounds like a confused person.
It sounds like there are no signs.
Tell him you want him back and if he doesn't want you after that then find someone else.
b freinds i had an ex now we're friends.but now he's crazy and i wonder,what was i thinking!
