Thinking more about what PF meant here:
Greasby received no response from from text wishing him happy Thanksgiving on holiday. Next day, #PatrickFrazee, who previously complained about “life” getting in his way, told her, “Life is about to slow down.”#KelseyBerreth @csgazette
“Get through tomorrow morning and I’ll be OK,” #PatrickFrazee added in his reply. #KelseyBerreth @csgazette

Life “is about to slow down,” because he no longer had the inconvenience of KB being around (as he saw it).
“Get through tomorrow morning,” would have been referring to the morning of the 24th, as after that, he would no longer have to worry about the bloody mess he left at KB’s house.
