I have a bat shit crazy mil and sil. Batshit sil is dbros wife. Mils daughter, dhs sister is fantastic.
Both our oldest are a few weeks apart in age. We have never competed, she is bloody great. We are going out with her and her husband for my birthday and I can't wait. Wish they lived closer.
Dbros wife was fine until they got engaged then all hell broke loose. She even had a go at my mum for offering to chip in for the wedding. Just once offered to help out. Apparently that was over stepping boundaries and stepping on her mums toes.
She is super competitive not she has kids (both younger than my two) if my kids are sick, hers are sicker. My kids took up a sport so she sent her son to another sport then told everyone how shit my kids were at their sport and she felt bad as her two year old was a football genius. She cries off sick for every event for my family. At mums 60th birthday party she was so ill that dbro couldn't leave her and bring the kids. At my sons birthday party she was so ill she sent her kids with my mum and insisted dbro stayed with her. Mum and dad weren't amused when they dropped the kids off and her parents were there looking after her as well. 3 adults looking after her while she had cold.
She tried to ban me and mum from spending any time together at all unless she was there. If we invited her and she couldn't come, she expected us to not go as well. Mum didn't take any of that shit either.
She told me that her kids wee more important in the family as dbro was the 'first born' in our family and their kids are always more important.
The problem is I couldn't give a shit. Events are easier if she isn't there. I love her kids and love it when they are there. One Christmas she told me I was evil for working while being a mum and that she hated working mums. I laughed at her. The more I don't care and don't react the more ridiculous she gets.
Ignoring and moving on is far better.
