Feeling frustrated

with my friend and need to vent....
Okay.. so my friend is getting divorced, I have mentioned that before. I have helped her out on numerous occasions, to include watching her kids on the weekends so she could go to classes. I have her cats at my house right now...
She decided two weeks ago that she needed to go back to the states to visit someone, pulled her kids out of school, and asked me to watch the cats. She was supposed to come back on Monday. We discussed this in detail before she left, because she is supposed to watch Roxanne for me while I'm in Texas and was supposed to take us to the airport on Sunday. So I haven't heard from her... Sent her several messages, and tried to call her on her cell with no response.
I hear from her last night, she just tells me hey what's up, trips going good decided to go see my folks before coming back. (this was an email). So I emailed her back, and asked her to verify when she was coming home... She said, when do you leave again? So I emailed her back and reminded her that I have to be at the airport by 730 in the morning on Sunday, and that she was supposed to be my ride... plus take her cats and my dog back to her house. Her response... oh well, I'm trying to catch a hop sometime this weekend... I think I will be home by Monday at the latest. I will make some calls and get back to you.
How does this help me??? I fly on Sunday.... So frigging pissed. My trip has been planned, to include her part of taking me to the airport and keeping the dog since March. Now with four days notice I need to find someone else to keep Roxanne. I can't wait until this weekend to make other arrangements for her.
I checked into parking at the airport, and I think I will just drive myself. It is going to cost me a little over $200 to leave the car at the airport, not to mention if I have to put Roxanne in a kennel. So pissed right now...
And her precious cats are just going to get left in the house, with food, water and a clean litter box which means that she needs to catch a damn flight and come back... Unless she sends someone to pick them up before I leave. I am NOT making arrangements for her cats.

I'm gonna check with a neighbor tomorrow, she wasn't home today. She has offered kind of open ended to watch Roxanne if I wanted to travel, because her dog comes and plays with Roxanne in my yard. Hopefully she can keep Roxanne, if not I have the number for a kennel. Hopefully they will have an opening. That is going to cost 60 Euro... so around $85.

I can't take a taxi to the airport, because it is over 3 hours away. I thought about taking the train, but I haven't done the trains before and don't really think I want to risk my first time using the German train being when I have a deadline to be someplace... I'm scared I would get on the wrong train... and then I would still need to pay for parking at the train station.

Its going to work out... I know that, I'm just irritated that she would do this. I understand that she is going through a rough time but I wish she would have thought about what her changing her plans was going to do to mine.
