Feeling angry. Is there such thing as to who is a better parent?

I am annoyed with my daughter's Father. We have been separated for a a year and a half. Heres the thing I love ♡♡♡ my daughter to death she is 3 years old and I have her for most of the week. I work I get her on the bus for school I do everything cause I'm the mom and I enjoy doing stuff for her. But when she goes to her dads on the weekend he goes out instead of spending time with her. Does this make me look bad if I am mad about him going out and not spending time with our daughter and he is old enough to know.?
