If a man cares more for a woman than one of his friends, he will probably try to become friends with her too, which is arguably a sign.
Stare at her. Tell her. Be smart
If you talk regularly and she says she misses you.
Look for the signs of pregnancy. If she misses her period.
A woman shows signs of being pregnant when she first misses her periods or when the periods are delayed.
If he has not shown any signs that he cares ask him, but if he is doing all that he can for you then every thing should be fine.
Most likely, but he could be giving you false signs. Try flirting back and see what happens.
A king writes laws, signs documents and cares for a country.
I think that its either: or
When he cares about himself more than you, or he nevers has time to go out with you.
It depends on his relationship with his current girlfriend. Are they having problems? If yes, then maybe he is interested. If not, then he might be just wanted to be your friend and actually cares about you as a friend. Or, he is trying to cheat on his girlfriend.
That he wants you to stop because he really cares about you.
