Last minute dates - dont feel like a priority?

My boyfriend and I have been going out 3 and a half years and yet, apart from every second weekend which we spend together, he cannot/won’t make plans during the week until he know his children don’t want to do anything or his ex needs him to baby sit (boys are both in their teens). I usually don’t see him at all during the week but if he finds himself free, then he’ll text me early evening / last minute to see if I want to go over to him or he to me. I get frustrated because I quite often have made plans already. He can’t understand why I get upset, but I feel like I’m always the second option. As a result we see little of each other. He doesn’t seem to have a problem planning a golf game though.
