I can't joke or vent to my husband

Because he judges me for being upset if I'm venting. He tells me I'm wrong, being unreasonable, and should just do things differently if something in my life is bothering me. If I'm joking about something, he tells me I'm not actually joking and gets pissy. He's just like his dad who can't joke around to save his life. I don't understand where his sense of humor went because he used to have one and he just sucks now. I feel so alone because I have nobody to joke around with or vent to, and my kids are haaaandfulls lately to say the least so I have all this steam I can't blow off by being light hearted and joking around or by venting about the kids because 100% of the time he takes their side and dismisses me. No matter what it is I attempt to vent about, he will side against me. It's almost like he's hellbent on disagreeing with me no matter what. I'm not looking to take sides I'm just looking to get things off my chest!

As for the joke thing, it's not that he doesn't laugh at my jokes that is the problem. I'm not trying to force him to laugh at my jokes. It's that after 7 years of marriage he still doesn't understand my humor enough to decipher a joke from something else and then when I let him know it was a joke he gets aggressive and tells me it wasn't. Like, yes it was??? I would know if I was joking or not... We used to have a fun relationship and mess around and joke around all the time. And now he legitimately has no sense of humor. Those things are what bother me.
