Sorry you struggled yesterday with anger. I struggle with it sometimes as well and from what I have read it is a healthly emotion as long as it doesn't consume you.
I can still hear some of the anger in your post. I understand the frustration about your H not seeing your son for a week. However, your son is also his son correct? There are plenty of people on the board where the spouse doesn't even try to see the child/children very often. I know it is hard but your son also needs his father in his life. I grew up and my father was never in the picture. This is some of the FOO that I struggle with and am working to deal with.
I also understand the fun dad comment however, I think time with your son no matter how it looks is really good for your son. I have to keep thinking in my mind what is the best thing for my sons. As much as I would like to have full custody of my sons it isn't in their best interest. My sons need their mom in their life even if she hasn't made good choices in our R/M.
Hopefully someday they will see the pain that caused to those around them. For the time being keep your head high and be the better person. You can't control your H but you can control you.
Glad to hear you went to the gym and channeled your frustration vs. getting in a fight with H.
Anytime he does something like this just think if him being around your son is the best thing for your son. Even if it is fun dad time I personally feel it is important that he is trying to be a part of your sons life. If the last minute request is what really bothers you then set boundaries around that vs. around him seeing your son at all.
