I wouldn’t do anything unless you have concrete evidence that abuse is taking place. Not to minimize the allegations of abuse, but the subject line is about how your ex brings new GF to drop offs and ends with how your daughter is scared to go to her dads because she abuses her, (along those lines). I will say don’t do anything that will make you frivolous to the courts or unbelievable. Do not lose your credibility because you don’t like your daughters dad bringing his gf to drop offs. I have sadly never met my kids step mom for 9 years and while we’ve have random exchanges, my kids had this woman come into their life when they were under 1 and 3. So that was concerning but I had to really trust their dad (who i didn’t!) that he would not allow his new gf to harm our kids and let go of what I could not control. They are our ex. We don’t have any business thinking we can control any part of their life. Do I agree with my ex or have respect for either of them and especially being a mom, she should have understood that a mom would want to know and meet the woman in her kids life. They got married and I still haven’t met her but my kids are 9 & 11 now and very close to her boys (step brothers) and the son they have together. I’m not saying abuse never takes place but I didn’t have enough to ever allege abuse. As a mom/dad, when you know something is wrong, you know it without a doubt. A forum won’t solidify your concerns especially if abuse is a concern. If he’s a good dad, he’ll protect his daughter.
