I'm not going to include my husband into my new friend group
Is there a good reason behind that?
I just want to get back at him for spending most of my money.
That is not the best way to handle a situation. He'll have no idea why you excluded him. Being direct will yield far better results.
I just want to be happy! Fuck dude, you don't understand me!
I understand that you're rightfully upset that he spent your money; I would feel the same way. So now what can you to keep something like that happening again? Excluding him from your social group will only confuse him and make him mad.
