my first girlfriend was a horrible cheater who used me for all my money. when...

[Jason]

...i find true love how good is it? i probably had one of the worst first girlfriends ever.  im 19 and didnt get my first girlfriend until last august.  never been kissed or anything, and im a good looking guy, dont get me wrong, im in great shape, i was just waiting for a good girl.
well my ex at the time was 16, now 17, and we dated for 11 months.

in that time, she cheated on me 4 times, never once bought me a single gift, i spent at least 4000 bucks on her, got her a promise ring, spent 700 for her and her family at xmas, she broke up with me the week of my bday, compared me to other guys, and broke up with me numerous times just to do it... then when we finally did break up for good, i got her 300 bucks worth of stuff and we made love and stuff, next day she changes her number and ignores me for two weeks, gets a new bf then calls me wanting to be friends....

i was a clingy whipped guy i'll admit, and after hanging out with my friends today and helping him move, i realized how good he and his girlfriend are,  they broke up for 8 months and didnt takl and finally got back together and they really do have a true connection.


my question is pretty simple....

When I finally move on past my ex, and get a great amazing new girlfriend, will my ex get jealous you think?  how amazing is TRUE love, where both partners share everything equally??
is it true that ex girlfriends come back if they see their former bf's happy with a new girl?  




details:  we have been broken up since july, i havent talked to her in 2 weeks, last time we talked, she denied we ever had sex or did anything together in front of her new boyfriend.. she lied to him and me, which is why i never wanna talk to her again, thats so low..
