I despise my sister's fiance and I can't conceal it any longer. He doesn't even consider her to the point where he takes the car to see friends while she is forced to carry home heavy groceries for 30minutes, in the rain. He is using COVID as an excuse to keep her from her family and friends, while his "bubble" seems to include whomever he wants to socialize with. She is joyless from working all the time to support them as well as taking on all of the household chores because he is "focused on his music". He controls their social calendar and prioritizes holidays for his relatives only. If I want to see her these days, I have to expressly invite her over to my house and even then he comes along and is surly and miserable and an uncomfortable cloud hangs over his area the entire time. The only thing worse than how he treats her is that she said "yes" and actually wants to spend the rest of her life living like this. I am worried as I haven't seen her smile or her eyes shine in all the years she has been with him.
