There's no real way of knowing for sure.. But I think everyone will always have feelings for their exs. Most of my exs have made me into the person I am today. Yet you just have to trust your partner, and realize that everyone has an ex and some CAN stay friends
He still wants to be with you if he calls and is concerned about you
If he's still calling ..
you would if he is still in love with his x is if he blushes or smiles or keeps on staring at her.dats how u would know
He wants to know how you are doing and still loves you.
i think it means, she just wants to be friends, but still be really close :)x
If she still wants to know what is wrong if you are sad. If she tries to make you laugh all the time. If she still cuddles up to you when you are hanging out with her.
if he still wants to hang out with you Eg: the park, the movies, a party, anywhere.
it means he is interested about you and wants to know more. maybe he wants to know more but doesn't know if he can ask you personally. it's a good sign :) depending on what he was asking of course x
She probably wants to get back with you or she wants to make conversation because she wants to be your friend
He probably still wants to talk to you, because maybe he is still a little bit interested in you, or he just wants to be friends...
Talk to him about it. That's the only way to be sure.
Stop dating him immediately. He doesn't know what he wants and/or he is playing you.
