So, my brother recently met a girl from his work (He's an audio engineer) and they ended up dating each other. I am happy for him of course and wish them both the best, but I am trying to find her appeal in him I am not being rude or mean here, I want to know what she finds in him that has her wanting to stay with him. I am trying to figure out what I am doing wrong in my own relationships differently. I've met people in person and had a nice time and all but they never stuck around or ever wanting to commit to anything serious with me.

I've known my younger brother all my life and he's a good kid of course but his personality I have always deemed as a bit abrasive, distant and aloof, he hardly speaks, keeps to himself has a bit of a temper and is irritable sometimes. One thing I do truly admire in him is his honesty, he is very straightforward and doesn't sugar coat and I really respect that, I can be a bit of a people pleaser and try to always fit in and match other's energy and try to appear outgoing and fun, I noticed this on vacation with him to see family just how different we are.

Everyone I have ever interacted with irl says they like me, I get a long great with everyone and I enjoy being with my friends and even my closest friend says I am a great guy, hell even past romantic interests say I am a great guy. So what is wrong with my romantic life then? If I am such an amazing guy, where is my partner? what is my brother doing right that I am not?

I met a woman a few months back and we get a long great and she says she likes me and we both are seeking a serious relationship and all that. But, she is talking about leaving the US and I'm just confused by it all. Maybe I should stop investing and relying on one person all the time and just start "bulk" dating haha idk anymore maybe I will embrace polyamory or something
