I'm not sure if this is worth going to therapy over but I always get irritated/extremely (basically irate) at my partner because he'll say "Oh yeah, I'm free tomorrow" and then goes on to do several things and then by the time he gets home it's like 9/10 PM which is around when I go to sleep. And I'll say "you're /Sure/ you're free?" Just to confirm and he'll say "Oh yeah I've got nothing going on" and then this happens. A lot (Almost every weekend at least one day a weekend to several days a week) Is this worth getting this angry over, especially since I've told him to not do that to me since I hate being let down? It just seems like every few days this happens and it's starting to really annoy me. He spent the entire day with me yesterday and I feel like maybe it's just me because I don't really have much of a life or many friends.

I've told him how it upsets me and he said he'll be more careful about how he phrases it, yet it still happens and I don't know how to deal with this anger I have about it and I end up just ignoring him after this happens because of how upset I am over it. Am I just being ridiculously petty?
