Get the impression many girls pass over me for the same reason

Why would it be a big deal? I'm an introvert myself and prefer a few close friends to loads of aquaintences who I hardly know. I don't get it when people go out in massive groups - you don't even get time to talk to anyone

Anyway OP I don't think anyone cares that you don't have many friends

I don't know just seems to be many of the women where there has been attraction have opted for another guy that I often get the feeling they are not as attracted to but see them as a better fit as they are more socialable, i.e have friends, better at interacting. So it kind of feels like a snub to me for not being good at this aspect of life, I would if I could but I can't. So I kind of get fed up of going round the same old circle that seems impossible to get out of. It's just something I feel many women devalue men a lot that aren't good on the social front and kind of look for a way of getting away from their feelings for you by seeking a more social guy even if they are not as attracted to him. It's kind of frustrating, kind of the way it looks to me anyway. I mean I probably do come across as pretty on my own and socially awkward/quiet at social gatherings.

Depends on the woman - if she's like me she won't care, in fact, introverted guys are great IMO. I have no interest in a party animal.

But more extroverted women might

Hmmm, think you could be right. Guess the thing us there often seems to be attraction to more extroverted women, not entirely sure why, maybe they come across as more vivacious, or they have something I don't, more extrovert, etc and vice versa. Again I don't really chose, its just where the chemistry often seems to be, an introverted woman would be easier for sure but they rarely seem attracted to me, although you wouldn't have to to be very introverted to look extroverted compared to me I think. The latest girl I have been interested in isn't an all out party type that some of them that have turned up, still she goes to parties here and there and is more outgoing than me. So don't know what to do really.

Get some friends somehow. Women generally like a man to have a social life .

Also are you sure these women aren't attracted to you? I come across as very extroverted but I'm actually not, a lot of people are surprised when they get to know me how "quiet" I am for lack of a better word, as they assume because I'm confident and friendly I'll be extroverted.

Have you spoken to this girl?
