Usually if a guy likes a girl he will try to initiate conversation.
He gave you the key because he wants you call in to him probably when he is in bed or if he is out that you will be there waiting for you. You could have fun with that; call over when you know he is out and be waiting there in his bedroom for him.
If he wants to marry you, he will ask you to marry him. If he has not asked, you need to talk about it with him so you are not waiting on him for no reason.
They really would like to know, what you are doing and who you are with. He is interested and wants to know what you like to do.
Simply talk with him and find out. There is no sense waiting for signs or some special treatment.
this means that he really really like u that is why he said he wants to know you
that just means they actually wants to breakup with you and he is scared to do it him self or he just wants you to know how he really feels.
Ask her
you can know by asking him. but if you don't want to seem to rediculous, you can wait until he makes the first move because he will if he really wants whatever he wants.
A guy would usually be hitting on you because he is interested in you and most probably likes you. maybe because he really likes you and wants to ask you out or he just wants to get to know you better.
Ask her! Only way, really. (:
it's highly likely that he wants to ask you
I'm a girl so I would know. You know if a girl really wants you by: 1. The way she looks at you 2. If she flirts with you 3. If you go out with another girl, she's jealous 4. If she talks to you all the time 5. If she stalks you 6. And finally if you like her ask her out! Then she'll know your not chicken! GO GET 'EM TIGER!
