What is love suppose to be?

i met a girl last year, im 28 and never been in love untill i met her, but as soon as i layed eyes on her i knew :) i got to know her through facebook lol we never met before but after a few months of chattin back and forth she gave me her number and we arranged a date :) i knew as soon as i saw her that i was head over heals, on our first date i even asked if she beleived in love at first sight and she smiled and said she did :) and i left it there, we had a great time, a lot of dancing and drinking and eventually kissing ;) she told me she had a son which was fantastic as far as i was concerned, a 4 year old boy, i knew this anyway from chattin on facebook, i had the best night of my life, then i dropped her off at her sisters and went home ( the taxi cost me 50 quid but i was on cloud nine so didnt care) i txt her the next day asking if she had any regrets and she said most dfinatly not, things were goin well, i was happy for the very first time in my life, we kept on txtin each other for the next 2 weeks then went on another date, this time she looked tired, like she had somethin on her mind, and she told me some other things about herself, how she had been raped, married twice and had a string of failed relationships, also that she had 2 other children, an 8 year old and a 9 year old who she said she had to leave behind so she could get married to her 2nd husband, the father of the 4 year old, she left her kids with her mother and moved to scotland to make a go of it with him, but it didnt work out and she moved back home and found her own place but still left her kids with her mother, she asked me if i hated her for not tellin me sooner and i said of course not, she was crying and i comforted her and we offically became a couple :) after our 3rd date we made love and i told her i loved her and she said it back and i was so fickin happy i cant describe it lol over the next 6 months we talked about our future, she told me she had a dream where she had my baby, she said id make a great dad, and she wanted to move in together and get married, she even said she wished her son was mine, she spent time with my family, she was at my house most weekends with cameron ( the 4 yaer old) we went out, we went christmas shoppin, we made love a lot :) but in all the time we were together i never once went to her house and met her parents or other children, i invited myself plenty of times but she always said no, claiming her flat was a mess, but i still thought things were goin good, boy was i wrong :( she spent xmas and new year with me and my family, she went home after new years day and we broke up mid february, but between new years and mid feb i only saw her once and spoke to her a handfull of times, she came to mine 1 sunday in jan for a couple of hours, hardly said anythin and then went home, she phoned me and told me i dont know what love is, i asked if she wanted to break up and she said no, but the next time i saw her would be my last and i dont blame her, it was all bottled up inside me, the frustration and wondering what was goin on, and we ended up arguing cos she flirted with someone right in front of me and i said if i did that you wouldnt like it, she said it wouldnt bother her and i said bollox it would, i said im going home are you comin, she said only to get her things then im leavin you, and i shouted a bit, said some things i shouldnt have, be them true or not, i never insulted her tho, or called her any names cos im not like that, iv not seen her since but i have emailed her, probly to much, she ignored me at first, but i wouldnt give up, so much that she hates me, she called me a sad pathetic loser and a stalker, a month after leaving me she moved in with a new fella, i gave her a ring for xmas, the most important thing ive ever given to anyone, so i asked her to send it back, cos that ring represented my love and she didnt want my heart anymore, she said she lost it and the oyer things i got her were goin in the bin and if i ever emailed again she would call the police on me lol iv not spoken to her for months now and i know she doesnt love me or even like me one bit, shes moved on, but i cant stop thinkin about her and im well and truely devastated, im still so much in love with her but i know i cant have her, if anyones reading this im sorry to bore you lol but it feels good to write it down, and if anyones got some advice id hear it
