I recall just prior to my split my W went to a movie with a friend ... Most likely was OM but at the time I was still in the dark, around 11 I TM her as you did... Worried... Was informed I need not worry, she was a big girl and could take care of herself. I used this every chance I got... I did not get here till way late in my sitch but this did help me detach a bit when she would try to pull me in and cake eat
She has this all going her way ... Everything... She is better at the manipulation game than you will ever be.... You need to get off her roller coaster for a bit and focus on you. If you've made plans with the kids, grab them and do your thing before she has a chance to plot. If she stays out till 9 a.m. .... Is that disrespectful? Sure.... But in her kind you are nothing more than a grumpy Roomate who stands between her and happiness
Time to figure out what you want ... She is not respecting you currently and she can not love a man she does not respect .... Use this time to become a better man, and do what you need to do to protect yourself
