I'm not a cupid type person, I have no idea how to set him up with someone. I see him only because we're good friends, we're not around eachother's friend groups as much as eachother.
Have you ever had that thing with someone where you both have some sort of connection that seems to go above the realms of friendship and even without telling them you know it's there? You're both clearly attracted to eachother in terms of personality (possibly otherwise, but that's not necessarily what I'm talking about here) and when you talk to them there's just something that sort of clicks? I don't know how to describe it really, but it's something you only really get with people you know you're not "just friends" with. I had it with my ex boyfriend automatically (though it's not always as soon as you meet). We met at a social between our unis and he was sat next to me. We didn't start speaking properly until halfway through the night and as soon as we started talking it was like something just clicked and we spent the rest of the night just talking as though we'd been friends for ages. We had the same sense of humour, some of the same interests and the same way of thinking, and even if we didn't have something in common we'd both be interested in it anyway and we even had debates sometimes but in a good way.
And before anyone thinks anything, this guy wasn't the first guy I noticed in the room before we started talking, in terms of looks I mean. I saw someone much better looking and we were talking too, we got along but there wasn't the same "spark" there and even though he was the first person I noticed in terms of looks I wasn't interested in him as more than a friend.
People also used to tell me "I could do better" than my ex-boyfriend (not particularly good friends of either of us) and I didn't care, because I loved him.
So it's not a case of going for the best looking guy or anything, but it's a combination of factors and I found my ex good looking even if he wasn't typically the guy I'd instantly see in the street and find attractive.
