I agree with Shiney, These are his kids also. As a man I work and do all of those things. I still have time for my D. When my W needs time for those kinds of things she just has to say hey I need to go and do this take care of our D. So what I would do if I were you is you need to go shopping. Get ready plop the kids with there Dad say I will be back in 2 hrs and then just go. It is possible to watch football and take care of kids at the same time. I know I ahve done this.
I just think its time to start asking for what you need and then doing it.
