Am I wrong for being mad and frustrated?

My Ex wife was suppose to come over today to take the dog for the weekend. She messaged me this morning saying she would be over after shopping with her daughter, ok not a problem. So I cleaned the place, took Remington for a walk, fed him, took garbage out and she still wasn’t here! So I messaged her and got no response. Finally at 6:30 she messaged me saying she fell asleep and she wasn’t going to come get Remington tonight but she would be by during the week to see him and she would take him all of next weekend. Am I wrong for telling her not to bother coming at all to get him this week or next weekend? Clearly she can’t be trusted to do what she says she’s going to do so why should I keep altering my plans? Welp that vent felt good! Time to smoke another blunt
