Misogynistic jokes

My (39F) husband’s (41M) birthday was earlier this month and I planned a late surprise birthday celebration.
This party was entirely planned, and clearly (emphasis on surprise) paid by myself.

We had a little over 70 people at the party, offered live music, cheese boards, snacks, free flow drinks, waiters, lunch, late night dinner…the works.
The people attending the party were mainly his family and friends.

We have worked in the same company for many years and we are fortunate enough to live a comfortable life in terms of finances, we have no kids and the bit during small talk with me is usually work (you work too much, you should take a brake), this is important to mention to give context to my annoyance.

I heard the same joke at least four times during the party from both man and (saddly) older females.

The joke was a line similar to “awesome party, thank you for having us I am sure this is a great surprise..(then directly to my husband) I bet the bill will be another surprise” someone even went as far as asking directly how much he was paying for it and how much I.

Today we went to another much larger party (120+ people same family) organized by a couple and not one comment was made, not one question asked about the expenses, no one asked who was paying for what or how much.

I can not express how disappointed the jokes made me feel…as if woman are still 100% dependent on their husband’s finances/money, people assume the woman can not pay by themselves for treats/trips or partying.

This is just to vent and as a remider that we have a long way to go.
