It requires a lot of preparation to level set to avoid misunderstandings about what this is and what it is not.
And this is where it quickly falls out of feeling like a true vacation to me because I am constantly negotiating in my head before, during, and after the trip/vacation. We invite AP to all local fun events...sports events, day trip to the beach, family dinners out, movies, bowling, ice skating etc. We pay for everything and AP is not working even for a second.
I no longer take AP with us on overnight vacations. First, I have three school age boys so who is AP going to share a room with? I am not paying for a private room. And I don't need AP's help. Even with our best APs, I need a breather from the AP dynamic. I want me kids to myself. I want to walk around in my underwear, flirt with DH at dinner, have an extra drink, and just not have AP's comfort and happiness on my mind.
I am also a rule follower when it comes to this program. I don't need anything else in my life to take up space in my brain. I think it has served us well as we have never been in rematch, needed LCC intervention, etc.
I think it is really nice that you invited AP. But, my biggest fear is that something goes wrong between your mother and AP. It is one thing to "get along well" but it is a completely different thing to share a room together for a week. This would just not be a risk that I would be willing to take. Especially only knowing someone for a few months.
