I like my brothers best friend🫣

I need advice!!! My brother has this one friend who I met at my brothers wedding, we didn’t talk at all alone, only in a group setting. I’ve known of him since they’ve been friends in Highschool. He hasn’t ever really came around like my brothers closer best friends, but he also is 26 and is a sheriff so he is busy w his career. I’m 23 almost 24, and I recently got out of a 6 year relationship about a year ago. I’ve taken so much time to heal and focus on myself and I’m definently not the type of girl to go out and get rebounds to make myself feel better. I value my relationships and I don’t entertain the idea of being with anyone unless I really like them. So randomly like 5 months post wedding, I’ve been thinking about this friend and I don’t know why. I want to talk to him so bad and I don’t think my brother would have an issue with it because his friends have similar traits and characteristics as him, they’re all genuinely good guys. After my previous relationship ended, all my brother wants for me is to find a good guy who is going to treat me right. I followed his friend on Instagram, but he doesn’t post on there and you can tell he doesn’t use it. He followed me back and after he followed me I saw he added a profile picture (it was blank before). Am I reading too far into this???? I feel like I am, I want to reach out but I don’t know how. I don’t think he would ever reach out to me because of my brother so I kind of feel like I have to make a move or else nothing will ever come if it, and we will never get to know eachother even as friends. Has anyone been through a situation like this before, if I messaged him, what the heck would I even say?!
