Engagement shoot

Our engagement shoot was originally January 30th and I scheduled this mid-December with our photographer. She emailed me Thursday asking how I was and I responded and asked if we were still on for the shoot date (mostly to be nice). She responded and said she was moving that day and had to cancel our shoot (???). The options she gave us (Friday night) was to do our shoot that Saturday or Sunday or extend out to February 27th. Our plan was always to incorporate our dogs and we both had appointments scheduled for hair cuts, makeup, etc prior to the shoot so between all that and asking someone to help with the dogs on short notice just wasn't going to work. So I said we would both rather do the February 27th but it's delaying our save the dates and a big bummer. Then she said February 27th was no longer available and we can have March 6th. She also says it will take 4-6 weeks to get our pictures back so that's April 3-17. Its still about 6 months out from our wedding but i'm just irritated that it's even happening and am looking for other thoughts. How can I trust her to show up to the wedding if this is how she runs her business?
