Curtesy invite

So I've had a friend who lives nearby.She is there on my Fb and I get updates about her hanging out with other folks from our community always but I'm not invited there.She rarely talks with me and it's been a while we had a conversation.Our friends are not common and it's awkward for me to crash at a place where I hardly know any.

Now she send me an curtesy invite over a text for a weekend party.Should I go or should I not ?
