Sometimes I think that the reason I don't end up with a nice guy is that it's just so alien to me

When you didn't grow up with it, you feel out of place in the presence of a truly caring person. Like they are on a level that I don't belong at with them. I'm not saying that I'm a mean person, I genuinely love and care for people around me. But there's still this glass wall between giving that out and receiving it for myself.

Can anyone relate to this?
