No its not about attractiveness at all.
I went out with this guy who was gorrrggeeeous I mean way out of my league don't have a clue why he liked me. And he was intelligent and had a decent job, fairly good conversation, we liked the same things but something about the whole dating thing wasnt right and it wasnt that I felt intimidated by dating him or anything it just felt like a massive effort all the time, and if it feels like an effort you shouldn't be in a relationship with someone. So thats what I told him, but I met someone else soon after and that didn't work out because they werent as keen as I was but being with him wasn't so much of an effort even though he wasn't as attractive and we had less in common really. DOn't know what it is personality, chemistry between people. On paper the first guy was more attractive (not just physically but the whole package) but thats not how it worked out.
