Raele Altano advises someone whose spouse mocks their laugh. Don't laugh along in public. Address it privately that day, explain it hurts, ask them to stop, and remind them respect matters in your relationship.

First of all, I'm so sorry that this is happening. I've been getting a lot of comments like this from people saying that those closest to them, their spouses, their partners, their parents or siblings, are the ones to mock and make jokes at their expense the most. In this case. I think it's really helpful that no one else is laughing. You should also not react or laugh in public, but that same day or night when you are both home and in private, you should find an opportunity to speak to him, let him know that you've noticed it's happened a few different times and and explain that it feels hurtful and you feel belittled when he makes fun of your laugh in front of other people. I would also establish a very clear ask and expectation. Ask him to stop and say, can you please not do that again. If he tries to justify or downplay his actions, you can say, that doesn't change how it makes me feel and what I prefer moving forward. If there is love, care and respect in the relationship, it should not be a problem for him to put an end to this immediately. Good luck and I hope this is helpful.
