I am sorry that OP is going through this. Hang in there OP! I wish you a positive marital counselling experience.
That being said, I agree with other posters who have said that there is an issue with OP's husband. Based on her signature, it seems they got married at a younger age, and so if they dated for awhile, it would seem that they have been together for years. Has it always been like this? What was it like before you were married?
I see a big problem with how the husband is acting. He is acting very hypocritical, and is sneaky in that he is taking his wife's side to her face, and taking his family's side to their faces. He is playing both sides because it's convenient for him, but this is causing big problems in his marriage, and that is not good!
Unfortunately we have to pick sides at certain times in our life, and since husband's family is treating wife in a negative way (and I am not happy with how they act in front of the children), then he must say something to his family.
He needs to stand up for his wife, and that is step 1. He needs to tell his family and show them that he will not tolerate the abuse they have shown to his wife, especially since she has anxiety and depression. This should be a no brainer for OP's husband. It should be about creating a positive and caring environment, and not one of intolerance and rudeness.
As for the party, SIL did exactly what she wanted to do (BTDT with my SIL) without any care for her nephew. She is immature, as is the rest of the family.
At this point, I think marriage counselling is a good start, and over time, individual counselling may be a good idea as well, as husband needs to learn what his role is as her partner. And his role is definitely to set things straight with his family in regards to how they treat his wife.
I wish OP well. It sounds like she is burned out due to a very busy life, and I don't blame her.
Best of luck, Tiger

, and the most he will help you with the children is 1 night out of 7
. I'll pray for your patience, because if I pray for your strength you might beat him with it 
Try not to bring your FOO in your marital problems (BTDT got the daggers to prove it). Knowing all he has put you through and how much you have been hurt will never blow over with your FOO. If you choose to stay in your marriage your FOO will always hold what he did to you over his head. They will never see that you have forgiven his past transgression and moved on. It would not be healthy for your marriage if you and him could not be made whole again. Having your past rehashed over and over would get you no where. Good luck and take care
