Honestly I don't see my MIL being a problem (she did ask me about the BF but once I told her no she was very supportive and dropped the subject). It's this particular aunt--don't know if she means it as interference but that's what it comes off as

I always knew she was going to ask about the cats and BF so can't say I was surprised at all yesterday when the subjects came up

Saying that I didn't take any offense to it, actually found the entire situation funny (as I said I'm quite stubborn and in the end will do whatever
I want to do)
