Most Helpful Girl
Depends on the guy.
If he seems like a well-adjusted, decent dude I will assume that he is like me and never bothered settling into a relationship just for the sake of it.
If he comes off as awkward or shy, I'll assume he's always had some trouble talking to girls in the first place. Not a negative judgment, just an assumption. He could be a really great guy, but he might be needy/insecure, which would be a turn off for me. If I find him attractive (pretending I'm single), I would go out with him, but first sign of insecurity and I'd be outty.
