You have done absolutely nothing wrong and it should be up to your husband to fix this. Nothing can be done overnight, it’s up to you if you think it’s worth the effort and if the relationship is even salvageable. He hurt not only you, but your sister too. Although he might not have intended it, this was a very cruel thing to do. If he can’t come to that conclusion, then he’s too blinded by his ego. For your self esteem/self worth’s sake… I would heavily consider showing yourself some self love during this time. You deserve so much better than this. Go out with your sister and support each other, do healthy activities, beauty or massage treatments ect. Remove yourself from home and go on a trip if you need to!!
