AITAH for not trusting my sister-in-law with our son due to her history with her own daughter? (r/AITAH)
I wanted to get some perspective on an issue that has caused friction between my wife and I as well as her and her sister by extension. Our son is 7 months old and on Friday night, my wife had booked a reservation at a restuarant and we were going to go to the city over and were planning on coming back late. Normally, her mom or mom and sister come over when we need to go out the two of us, since they live really close by. I remembered that her parents had flown out for the weekend and so asked if we needed to make arrangements. She said her sister was coming over (she lives with her parents).
I have nothing against her sister, its just her history with her own daughter. She had a daughter with her then boyfriend, whom she left with him. Her daughter was a year and a half old at the time. It was a whole thing at the time, I know my mother-in-law at one point had offered to move near their place and help with the kid, offered help, their family basically did anything they could to convince her to not do it, but she was going through it, I'd heard from my wife about her troubled feelings about her life, and she eventually left her daughter with her boyfriend and his family and moved back with her parents. Her and my MIL do often help out with our son, I just wasn't sure she could do it alone, that was my only issue.
I brought this up with my wife. She got defensive and said that was unfair to her, she's in a much better space now. She said it was the circumstances that had dragged her down. When I brought up the stuff she herself had told me at the time, she said her troubled feelings about what she wanted to do, were regarding herself, never her daughter. I said all that is fine and if it were a one hour thing that would be perhaps fine but this would take longer and we just couldn't risk it.
Fortunately, we had the conversation earlier enough in the day that we were able to have my aunt come over instead. My wife told her sister, and while she tried to frame it as a no worries its sorted call, my sister-in-law took it the wrong way and they had a heated argument. My wife has blamed me for it. Was I TA?
