What did I do that was so wrong?

I don't usually do this, but my hubby is really upset with me.

So, last week he went on a work-cation with 3 other guys. Might I add they are single and have no kids of there own. He's has 2 kids, 7 and 11months. Anyway, I was alright with him going and all. We are tight on money and he wanted 300$ to go with. Why? I don't know. He was only gone for 4 days. Well, he took the money and he was supposed to buy his car tag sticker before he left. Did he? No! I found that out later. So now that's late. I call him, he don't answer so I text him, he finally answers. It's like oh I can't call my wife because I'm with guys. Do what?! When he does come home Monday night at 845ish I had just put the kids to bed and he comes walking in and I'm so tired cause I've worked and took care of all things and cut the grass, which I don't mind at all, but I was tired. He walks in and looks at me, it took me a minute then he just stared at me. I said aren't you going to hug or kiss me he said well you should. Since I didn't give him a proper hello he's passed at me. And says it'll take time to fix this and that I don't live him. Geez, I love him so much, but I'm human and get tired. He said while he was gone he felt like him. He could be stupid and do what he wanted to do.

But we have two kids and our oldest is in dance and tumbling. I'm the one running her to them places and takes complete care of the house and outside. He never helps. Now, he won't look, talk or even act like he wants to be around me. What did I do? I'm so hurt.
