Yes, living with her as my ex-girlfriend is worse than living with her before, when things were not perfect, but ok.
I'll have the last laugh though: I turned in the earnest money check on Thursday. Hopefully inspection goes well. I haven't told her anything, so when the new place is fixed up, one day after she gets back from work, she will find neither me, nor my belongings where they used to be. These thoughts keep me in good spirits.
