she is the same age as me. . She lives with her family and works full time so definitely not moving in any time soon i don't think. . I don't want a serious relationship but I would like her to fall in love with me. The only time I think she has feelings for me is the few day period after we have sex. we had sex one time and she tells me "lets move to New York together"
Im sure you've heard this 5000 times
but at the same time, I feel like if she saw me with another girl it wouldn't bother her and thats a problem right there. She just strikes me as the type of chick who falls in and out of love every 5 minutes.
That's the perfect kinda of girl for me

Dude, if you're trying to figure out women and/or control their emotions good luck to you as it will never happen, take each moment for what it is and enjoy yourself....the latter should be your focus not this emotional girly shit. If you want her to fall in love with then IMO you're after some emotional needs to be satisfied via a woman's love...may be your mum wheened you off the booby too early, or whatever.
Whatever it is you need to get to the bottom of it. Personally I never been the kinda guy to fall in love easily, I think you're after emotional fulfilment more, don't pretend to be a player or try to be womaniser if its not in your DNA, do only what you are comfortable with, I think you need to knock this one on the head and find a more suitable girl who will be more committed to you from the get go and give you the reassurances you're after.
