I went ahead and told him I would get it completed by the end of the month. I really am surprised by my reluctance to take what is basically almost the final step to complete the divorce (the final step would be signing the final papers).
I spent a big part of the weekend doing handyman work around the house. There were two closets in the house with doors that didn't slide any more. STBX had told me they were just old and not fixable, (which I just accepted) but I had the time to take them apart and figured out that they only need new rollers, which after some trial and error I was able to successfully install. The front door has too much of a gap between the door and the jamb - but after exploring options (weatherstripping won't cut it), I think I had better leave that one to an actual professional.
I feel worn down. I'm taking the girls to Disneyland next weekend (I splurged and got us annual passes for the year) and I find I am clinging to the anticipation of a happy family getaway like a life preserver.
