You invited who on our vacation?

Friday night, it's the end of our fourth week of camp. Grewling 5 days a week, from leaving our house at 7:35 and returning home no later than 5 p,m.! Long days! All I want is a big old glass of wine, some take out food and my couch. Settling in and feeling relaxed. He says "I have some news" which always equals bad news to me. It's our short, three night planned vacation in R.I. He has in some way inadvertently invited his newly divorced friend and his son along by naming the place we are staying and the exact nights we'll be there! He apologizes and thinks that it's all better! I try not talking to him for about an hour and the wine along with camp nostalgia talking with my daughter get me to open up and enjoy the night. Oh well, what can I do at this point anyway. If I complain, I am the uncaring wench that has no feelings for the poor alone single father, sucky situation to be in. And then with just a little more each time I realize that it keeps chipping away at the positivity that I have left, which is very little at this point. What is there that I have to look forward to? What I thought was there, is no longer, something has got to give sometime. Sigh.
