I posted about this a long time ago, but I doubt anyone remembers the summary of the situation so I'll give a quick one...

BM cheated on DH with every single one of his friends and topped it off with a threesome with his blood sister and her husband at the time. DH found out from his mother (who was dying of cancer) on Thanksgiving. DH stayed with BM until his mother passed because he couldn't stand to have his mom worry about anything more than herself while she was going through her own battle. He filed for divorce a few months after his mother passed (after spending a total of 3 years with BM post cheating ordeal).

Anyway, BM and DH get along fine and co-parent and have zero issues for a year before I come into the picture. As soon as he and I became serious she went looney. She literally threw a temper tantrum over me coming to SD ballgames which included her launching a full beer at DH's head (which missed him and hit her own car, lol) along with her jerking the kids out of his truck (on his day with them) and him having to threaten to call the county on her if she didn't stop. She then proceeded to have a "panic attack" at work the next day requiring an ambulance ride to the hospital *eyeroll.*

Once she realized she none of her antics were going to work to control him, she stopped with the crying bs and started in with showing up at our house and beating on the door and blaring her horn and other crazy things to try and force her control over him.

When that didn't work she filed for full custody and attempted to make him an every other weekend dad (he has shared legal and physical custody which literally translates into him having them physically at our house more than she has them at hers). He fought back and won that case which resulted in nothing changing except her losing 30% of her child support and the court enforcing that she could not move the kids out of the school district we all live in.

Okay so here is what I have been pondering about her crazy logic:

Prior to me entering the picture and DH standing his ground with her she would attend everything the kids were involved in and she was very civil and even friendly with DH. Now that the above history has taken place, she refuses to attend SS basketball games or SD softball games if we are present. She used to come to SD softball games and take her to practice on her days and weekends when DH had to work, but since he started as the assistant coach she refuses to come to any of her games, and will not take her to practices either. If DH is working I have to go get SD and take her to practice while BM sits at home for whatever reason.

So... to summarize that long story, I'm curious as to why BM would participate part time on her own time until DH started coaching, and then once he started coaching she removed herself from the whole deal indefinitely. A parent from another team had asked about her over the weekend and commented that they thought everything would change when DH started coaching, and as I thought more about it later on I just wondered to myself, WHY??
