Ex girlfriend, new start. (long story)?

ok, right, i used to go out with this younger l when i lived in england, she was amazing, i treated her like ****. i cheated on her, got her to start drinkng, had unprotected with her when she was immensly drunk, i told her she was useless and i will admit i did hit her a few times and she did begin to self harm. so basiclaly, yeh i was a **** boyf. then she broke up with after half a year and i didnt see ehr much, and next time i saw her she had changed so much, and she was really happy and looked stunning, she'd got pretty popular, and she stopped self harming. i moved to spain with my mum (whos not really mu mum, she adopted me when i was one and she is incredibly rich) and recently ive become friends with the girl, lets call her beth. i really miss her and i wont hurt her again, and i really wnat to get back with her but her friends absolutely hate me and say she should block and delete me on msn cause she can do loads better :@. so i was thinking i should come to england again to see my boys, and i could like, take ehr out for a meal then take her to a premier inn & have with her, and get her pregnant, and she could come and live with me in spain and id look after her and the baby and everything. i have 4 kids already from one night stands and stuff but i dont care about them cause theyre with sluts, i really want a baby with beth, plus it'd be stunning cause it'd look like me and her :D dwhat can i say to her to convince her to come on a date with me? im 18 and shes 14 btw. but ehr parents would probably kick her out if she was pregnant
