The Last Hurrah

Today is it - my last day of freedom before my mother in law descends upon us. I keep reminding myself that it's only three weeks and that I get him for the rest of my life and she only has this three weeks at a time... still, I have to be honest, at least with myself, and admit that it doesn't really help.
For the next three weeks, it will take EVERY SINGLE OUNCE of love that I have in my heart for my husband, just to put up with his mother. Oh yes, she is a nice enough person. If it were just us, we would even be friends, but sadly she has turned us into rivals for his time, affection, etc.... and I am left with a battle that I never wanted. My days will be consumed with all the things that are wrong with my marriage, why my husband isn't happy, what I could be doing better, and how one single move is just so freaking traumatizing for my nephew when my daughters get to do it every 2 -3 years. Hello?? Talking to me about the stress a child feels over a move, is like bitching to a military wife about how much your husband works when you're a civilian and he comes home every night. I am sure that I will have the urge - at least once in the next three weeks - to happily rip her head off.
Robbie is already really depressed, so I already feel like the last lifeboat from the Titanic that is WAY too full as it is. I don't need her on top of it. I resent the fact that I have to share what little time I have with my husband with a woman who thinks that it's her right to be here, and she has absolutely zero understanding of the sacrifices that my children and I make.
Even worse, she isn't here to see my kids. She could really care less. She doesn't know who they are, and she probably never will. She's clueless. She's here for him - he's the main event. If he weren't here - she wouldn't be either. No matter what was going on with my kids. It just pisses me off.
I'll try not to drive you all as crazy as she is making me for the next three weeks, it's just that writing helps me cope. So sadly, you guys are probably going to hear a lot about it.
Positive thoughts and prayers are certainly welcome. I have a feeling that I am going to need them.
