MIL annoying over baby’s name

So this is really just more of a vent - I do know logically that words are just words and we of course plan to name our baby as we please. But my MIL just drives me crazy. She has emotional and substance abuse issues that we have been navigating for years. When I was pregnant with our first she was super adamant that it would be a boy and that we should/would name it after my husband. My husband has zero interest in a junior and we told her so. Then it turned out we were having a girl, at which point she made a point about her own name being a good name to use. We obviously did not use her name, and when daughter was born and we told MIL the name she must’ve asked 50 times if she was named after someone on our side (she is not, we just chose a name we loved but I think MIL is still convinced that it’s a name from my side and is resentful of that). Anyway now I’m pregnant with our second, a boy. She has brought up naming him after my husband again many times, to which my husband and I, both together and separately, have reminded her that we do not want a junior. Now she is going around telling people that the baby’s name will be the reverse of hubby’s first and middle name (which is not even a family name btw) 🤦🏼‍♀️ I’m beyond getting angry at this point bc it’s just pointless but it is just so EXHAUSTING. This is the same woman who told a room full of people that her biggest dream for this baby is that it looks like her, meanwhile she’s the type to be minimally involved in her existing granddaughter’s life but then expects to be revered as the special grandmother. Like I said, I’m beyond getting actually pissed over this stuff but I’m just so over it and over her.
