does she feel the way she says she does?

ok so i just started going back out with a girl i went out with 4 years ago.. we started back up october 9th. we hadn"t talked since i broke up with her on april fools day of 08. we're 18 now. i broke up with her before cuz we werent allowed to see eachother anymore cuz of her parents saying so. there was never really any closure and it was really a bloody break up for her. i know its horrible to end it like that we still loved each other i just couldnt go without seeing her so i had to do it.

So anyways.. now we're going back out. she s the only girl ive ever really loved and ive told her this. we've both changed and thats fine we both know this about eachother.. so she tells me she loves me now and idk if she really does. i told her i loved her last tuesday..

i just dont know if she does.. i dont know how she feels.. everything goes so smoothly and everything is cool between us.. im just clueless.. am i just blind to how people feel? am i stuck in my own head? i dont think i am but its possible.. do i need to try and step outside of how i feel? i am a buddhist and i am a very deeply emotionally run person.. i know about the power of love and understanding.. i just dont know if this is love.. are my expectations of love unrealistic? i always thought love would be a warm feeling inside of me.. a strong desire to want to be with the person.. when im not with her time goes by so slowly.. seriously yesterday was the longest day of my life and im not just saying that to be saying it.. can anyone tell me whats going on? i need some help cuz i really dont want to hurt her.. i care about her beyond belief and i know what shes been through and i understand that all she wants in life is to be in love and be loved and i dont want to deprive her of that if i cant give that to her.. i do love her but im not sure what love really is.. someone help me please
