Why is He Doing This?

I can't eat, he stopped by this morning and asked for something to eat at like 5 something. I made him some scrambled eggs. Last night I stayed up tossing and turning. He is back at the casino, he only took a couple of bites, asked for me to make him some coffee walked out the door with it and smashed the cup, said he had to get to the races. I missed the doctor's appointment yesterday, because I had no one to watch the kids while I walked there. He brought me a necklace he said he had found, and sent a $10 gift card through email for Walmart. We just got back from Walmart and Walgreens, got the boys some cheap toys and some garbage bags. Apparently he is waiting on someone or to meet someone there, I dunno.
