Is it a good sign if a guy invites you to his house party?

Anonymous
Long story short, this guy (I don't know him that well and met him through a mutual friend) asked my friend to invite me to his birthday house party. I wasn't able to go unfortunately, but was really surprised that the guy would ask me to his house party. I had met him a week before the invite at a dinner event.

A couple of days later, I found out that I was the only girl that he had invited to his house party from our group.

Is this a good sign that he's probably into me or was it a friendly gesture?
