Hello!! I hope my Japane will help your learning Japanese♪ Why are all the guys I like always so far away? 　どうして、わたしが　すきに　なった　おとこたちは　みな　とおくへ　いって　しまうの？ 　どうして、　私が　好きになった　男たちは　皆　遠くへ　行ってしまうの？ dou shite watashi ga sukini natta otokoto tati wa mina touku e itte simau no?

Dunno if you can read Hiragana / Katakana yet or not, but so far as I can put together, it'd be: どうしてすきなおとこはいつもとおすぎるの？ Doushite suki na otoko wa itsumo toosugiru no? (The too is pronounced kinda like to-oh.) I'm sure that native speakers could probably give a more colloquial answer, but I'm pretty sure that's right.
