He is an asshole

I need to document this quickly, while it's fresh in my mind. Today marks my husband and I's 10-year anniversary. We talked about our plans yesterday to take the kids to the library this morning for some age-appropriate programming. This morning he tells me he's not going to the library with us, and I explain that each one of us needs to accompany one of the kids, so both of us need to go. He grudgingly agrees and then yells at our one-year-old son because he is crying. I tell him not to yell at our son and he tells me that now I'm judging him/telling him how to behave. He then says sometimes it's hard. Then, we are talking about our plans for today and I told him I wanted to do something special for our anniversary, and say we could go to a bakery, or to a park, or a new place, or take the kids to their grandma's and do something. He says that he definitely wants to drop the kids off at their grandma's, and our daughter gets upset about this and starts crying. He then tells her to get over it, it's not that big of a deal. So, then I'm sitting in the chair with our daughter trying to comfort her and I tell her that I love her and that her dad loves her, and he says, "you don't need to tell her I love her, I already told her that, you don't need to make excuses for me.". Then I ask her if she would like me to accompany her to the library program or if she wants her dad to, and she tells me she wants me to take her, to which her dad replies, "I'm taking her because I'm not going to toddler time". So I said, "What do you mean you're not going to toddler time?" He then says, "I'm going downstairs to drink my coffee in peace". What an asshole. I need to stop thinking that I can fix this situation. My therapist is correct, I think, in stating that my husband is the source of my depression.
