how many of you have exs that have gf trying to be mom of the year??

sorry I have to vent my ex husband's gf is trying to text me all this shit saying I'm a pos mom bc she can't agree with the terms that me and the father of my kids have talked about of custody she is saying that I don't want them to see the boys and how I never come half way to drop off even tho the last 2 times I dropped them at there front door over an hour drive from my house she is mad bc my job schedule changed and it doesn't accommodate her job so she can pick up the boys I'm so sick of dealing with her I'm about to fly off the handle rant over am I the only one? ?
