I need some advice ASAP please

So this is going to be kind of a long back story but I will try to make it short.

Before my husband and I got married, we had a ton of issues in our relationship and honestly we NEVER should have gotten married, but we did, so what’s done is done.

The last few months before we got married he was doing so good. Making so many changes. Working his butt off and bringing home good money. We both were.

We got married and he quit his job. He refuses to work. I make minimum wage working at a liquor store and have 3 kids from a previous marriage.

All my husband does is sit around all day and play video games and smoke weed ( we have medical marijuana cards so it is legal in our state) I go to work every single day. I am working 7 days a week right now. Taking care of the kids, the house work. Errands. Paying the bills. I’m exhausted. We have had many fights about this and he always says he is going to change and he is going to do better and blah blah blah.

So tonight, I had to work an hour later and got home and just wanted food and a back rub. His friend is over and they are about to smoke. So he rubs my back barely for less than 5 minutes and then says he’s going to smoke with his friend and play the game for a little bit but he will give me a better back massage later.

He has been playing the game alllll day. Since 12noon. And it’s almost 930 right now.

Would you be offended that he made you wait? Am I over reacting? I just want to cry. Guess I’m going to go take a bath and hope that helps my back!!
