For her to tell the people she wanted you to meet that you didn’t want to meet them, you must have told her something similar.
Regardless of what you think the facts or reasons are, in relationship terms you’re in the wrong. You need to man up, accept it and say sorry, and only when she accepts your apology, explain why.
But I understand where you are coming from… I used to feel/act this way often, but in a new relationship in the last year or so, can’t get away with this any more. You have to make an effort and work the room sometimes. It gets easier, and it pays off.
