Pleeeeasee help me choose >.>?

Hey People, im female 21 years old, college student.. attractive.. all that good stuff. Anyways, I was wondering who I should go for. There's alotta guys that's after me, and im newly single. I dont really wanna rush back into a relationship... but at the same time; being single sucks >.>. Anyways... i've narrowed it down to two guys, 1. My ex: we are still on good terms, but we broke up because he wasnt affectionate with me and only wanted sex, after breaking up we argued alot, deleted each other from Facebook, and such, it got real nasty. But then he texted me outta the blue, saying sorry.. and he misses me and stuff. Then 2. My other ex, we broke up because he was still in love with HIS ex, but now he's like. hooked on me. He buys me anything I want, he always takes me out, and pays for everything, and he is extremely affectionate but he's kind of a push over. And I want a challenge.. idk, kinda like a "bad boy" Can someone help me choose?
