rsvp surprise! Long...

Just a little rant and hopefully some feedback. My invites went out 2 weeks ago, RSVPs are coming in!! It’s so exciting to see them in the mail. My wedding is going to be at a venue which has a seating limit of 125, we carefully selected our list based on family and close friends. We gave some plus ones and some not. Our decision on plus ones were based off married couples, live in or domestic partners, we have also chosen to have an adult only reception except for the children of the bridal party and local cousins. ORIGINALLY I was worried about my FHs friend pushing in his plus one, he is the playboy I wrote about a few weeks ago. He actually RSVPed with just himself based on exactly what I thought, his adventure girl didn’t last longer than a week. ANYWAYS so here is the SURPRISE, my friend of 33 years (known her since I was 2) received an invite without a plus one. Based on my feelings of her lifestyle I didn’t give her one. She is married, has a child, her husband and child lives with her mother, she lives with a man who lives on a boat and is also dating another man or two on the side (I do not agree with her life although I don’t judge I just don’t think it’s appropriate). When she sent her RSVP back she crossed out our 1 seat reserved for you in your honor in big bold letters wrote will be 2 seats in my honor his name is “*******!” TALK ABOUT SHOCK. My mom was completely blown away when she received this RSVP. I told her to let it go bc I’m not going to fight her bc we may have someone cancel and she can bring her date. But at no avail she is still upset. We actually had to leave our family to get some friends on our list bc we both my FH and I have huge families and I cut half of my cousins which was a very hard decision based on the amount of people included. I cut my family so his father would be happy (even though it’s his second marriage my first) Now I don’t know how to feel. I want to be upset bc of her audacity to do that without asking me first considering she was at my shower last Sunday and never mentioned anyone except the few guys she is having sex with. I think she assumes bc the size and way my parents are that it will be an expensive wedding with no cost thought, but I feel she should have at least ran it past me. If we have others do this or people show who aren’t invited our WP has been instructed to remove them. I don’t want to leave out my family who won’t come bc I couldn’t invite another person in their group but let my friends cross out and add who they want. Am I wrong to feel a little ticked?
