Please let us know how it works out. I hope your blues are temporary and you'll feel better soon.

$200 is a lot of money to spend a month on classes. But like what's already mentioned, your mental health is important. I spend $100/ month on Hot yoga without blink an eye. But I don't buy too many clothes or make-up to save for that. It's all about budgetting.

Has your DH always been cautious with how you guys spend money? If not, it might be something else that's bothering him. Hopefully, you guys can sit down and talk about it. Let him know what's been bothering you without blaming him or the in-laws. It is important that you express how you feel and not blaming anyone. You can only jusify how you feel. Tell him that this class would help you get out of your saddness and go from there.

Maybe he wants to help. Guys wants to "fix" things and find solution. Is the weather out there good enough that maybe the two of you can do some stuff outside (biking, skiing, snowshoeing??)
