I know this sounds really unromantic but no man I've ever been with has ever brought anything unique to me, they brought qualities I like but they all had the same qualities. Maybe the way I view things is different than you because you're asking one of those "fairy tale" questions, where you want me to make it seem like my fiance is this one of a kind guy that never existed before him.
You probably believe in soul mates too, huh? I don't.
Do you want to know what I love about my fiance? He's really nice, we get along, we both have qualities that other person doesn't have, like he's calm and I'm not and he's super romantic and I'm not (he would probably tell you something "unique" about me even though it's not unique). He's very wise, he's very straight forward, he can come off a bit harsh but he says it's because English isn't his first language. He's an introvert, I'm an extrovert, I like that because I like people to listen to me talk about nothing without interrupting. We share the same morals, we're both homebodies, we both have broad sense of humors, we live similar lives, I like spending money, he likes spending money on me. There's a lot that I like about him and a lot of the qualities he has compliments my life, even the things I don't like about him compliments my life. Like if he doesn't like something, he'll say it. Like if I'm wearing some thing that's ugly he'll say it's ugly even if I don't ask but he'll say
I look good but my outfit is ugly.
I also like that he knows when I'm joking and when I'm serious, like I can tell him to drop dead and he'll laugh because he knows I'm not serious.
See, I pretty much like everything about him (expect how brutally honest he is and how hard it is to scare him) but he's like clone of all the guys I've been in a relationship with, the only things that gives him an edge is his height, his income, and his accent. My dad even says that
I've dated the Mexican, Black, and Arabic version of the same guy. That's why I say he doesn't bring anything unique but I think he's unique compared to most men in the world. Does that make sense or no?
edit: damn I typed a lot, I'm sorry
