Ok, how do I respond to this text?
W: going to eat at 6:45 with (friends). If you want to go you can meet us there.

Not sure how to take that. Previously text would have just said, "going to eat at 6:45. See you there.

Can't really tell if this is an invitation or not. If I don't go will it seem like I am avoiding her or pouting? I really have no reason not to go except that I don't want to go if she doesn't want me there.
Thanks in advance for the comments.
