You’re not evil for thinking of how you feel about the presence of people being in the same space/house as you. Yes, as children we may feel obliged to take care of our parents especially when they’re in need. However, you should also be prioritised on how you feel about anyone (be it MIL,FIL,BIL, aunty,uncle, etc) being in your space. As with any 2 room flat, space is a big issue. Perhaps you can discuss with your hubs how long will this arrangement last. Plus, i dont want to sound offensive but when people threaten others regarding ‘karma’, i just dont think thats right. Do whats best for the family. At the end of the day, will u be ok if it affects your marriage in the long run due to this? I dont think so. Always, always prioritise yourself & your children’s need & happiness. Dont be ashamed or scared to speak how you feel! ❤️
