Should i break up with this guy?

I met a guy on FB, I'm in US he's in UK. He's everything I've ever wanted, evn though he's 7 years my junior. For the longest time I kept platonic bc I loved his personality, talent,innocence - and I dont want to go to jail as a female mild pedo :/ I had him to myself at first,til he told me abt a girl @ his school who askd him to draw her. I didt want the comp, but I felt that I'd be a creep and a bad friend if I dint give younger girl a chance. I gave some advise, he got her, she dumped him. He got suicidal, I told his cousin, who told his mom, and saved him. L8tr he met a singer at a concert, let's call her G, who gave contact info. At first this girl was just an off/on pen pal. Then suddenly after I was starting to like him more, she went CRAZY for him! The worst thing is, as she started keeping up with him better, he asked for advise on what to say to her. I foolishly gave him tips, wanting to see him happy. Now I've got myself the TOUGHEST comp I could have ever asked for short of Megan Fox. I'm not that bad looking, but I'm poor, very shy, and not very popular at college (I always ended up with cripples n such as friends evn though I'm not 1). She is vry rich, and prolly doesn't hv acne like I do. Weirdly enough, I almost didn't mind her at first, but now she wants sex with him! She already stole his first kiss - something dear to me that I would've cherished my whole life. He is a virgin, as am I, and I really love him. Today he told me that he really doesn't want to do it with me or anyone, but as he put it ''she wants to do it so how can i say no?'' She's 12 years older than him! Supposedly she's a virgin too, but I can't help hating her for this, and hating myself for helping him get her! I can't get a plane ticket to England - it will take me YEARS to get that kind of money :'( She may be older, but she has more money, she's a good singer, and she ain't bad to look at. In add to her, after he met me he's now a girl magnet...I've FOUR others to compete with, one of whom is an actress and his 2nd cousin (not the incest kind). I hate the cousin - she'd never met him in person b4 and wantd to do him after meeting him only 3 days! Some of these girls are darn fast too, kissing him the 1st day they meet him! Seen proof of the cousin, too. All these girls are rich, good looking, and some r actually nice. Should I keep trying? He tells me he loves them all and me too, he wants to visit and he's a rare find, but I don't feel like I could ever win. The only advantage I have is having saved him from a suicide attempt. Should I evn bother anymore? I almost broke up with him today. I feel like I'm fighting a losing battle, like I got sent into the battle field with a kitchen knife (prolly a butterknife, dammit), trash can lid for a shield, while these girls have samurai swords and riot shields. What would u recommend? I can't tell him to drop em all - specially not G. I feel like I should give up, is this normal?
