Baby shower

I told my husband we had to pay $25 towards the venue for our baby shower this Sunday. My mom was supposed to help, but she was laid off from her job and isn’t able to help as much as she would like. He threw an absolute fit, acting like a child and told me he wasn’t coming because it ‘doesn’t benefit him anyway’. He just gave his sister, who I might add is heavily addicted to pain pills and has no job , $20 for ‘food and coffee’ for college after I told him not too since obviously I know what it’s actually going to. I’m so over him anymore. He acts like it’s such a bad thing to help my family out when they need it, but is so quick to hand it out to his. We have a joint account so it’s both of our money not just his or mine.. ugh..
