Does she feel the same?

we've been dating 6 months. the other day i told her i loved her. she smiled, said "awww, that's so sweet" and then kissed me. she didnt say it back though. well, we have this thing we do. for instance, if she says/does something stupid and i give her a funny looks, she smiles and says "hey, you agreed to date this" ('this' refers to her). when i do something, i smile and say "hey, you chose this" ('this' refers to me). well, today she said that but she said it differently. this time, she said"hey, you agreed to this and you said you love this" and then she smiled. do you think she will say it at some point. i mean, i only want her to say it when she's ready, but she will say it sometime though won't she? ive noticed lately, she is doing new things. she will take her foot and rub my leg, she will rub my side, and she will put her arm around my waist. she's starting to get closer to me. if it helps, im 21 and she is 19. oh and after i said "you chose this", she said "yeah and no regrets". it is also worth mentioning that she was the one that asked me out. is it possible that she feels the same about me?
