My ex-wife got my daughter's ears pierced and put earrings in. This bothers me but there's nothing I can do about it.
I wasn't going to post this, but decided to so that you might understand how blessed you really are that the seeming worst you've ever seen is that your 5 year old daughter has had her ears pierced.
I'm not saying that because I agree with what was done to her. I'm saying it's a good thing in a lot of ways that you haven't been exposed to a lot of the evil that goes on in the world. I wish I hadn't been. I've seen a 3 year old little boy addicted to drugs because his father thought it was hilarious to see his little boy smoking pot. Even worse, the day I was there to witness this we were smoking opium laced pot and when that little boy got his hands on one of the joints he ran off and hid so he could have it all for himself. He was an addict at age 3. And this happened in the early 1970s. I've often wondered what happened to that little kid. He was a cute little kid, but his chances of having any kind of normal life were between zero and none from what I saw.
Parents doing drugs openly in front of their kids is actually a common event in this world. Getting their own kids high is less common but it does happen. Drugs lying around openly available to the kids is very common among heavy drug users.
I've known of mothers having intercourse with strangers in the same bed with their little girls. Other mothers who bring men home and lock their bedroom doors so the child can't get in for the purpose of having sex. And the daughters are old enough and seen enough things already in life at age 5 that they know what their mother is doing.
These are not uncommon events in our world, so if the worst your ex is doing to your little girl is piercing her ears, you're actually fortunate. Count your blessings that she isn't doing far worse. God is protecting your little girl from far worse things.
It's a good thing to be sheltered to a certain extent from the evil that exists today. I really wish I'd never seen all the evil I've seen and knew nothing about it except as remote tales rather than knowing about it on a personal level. I know, personally, a father of 6 who when his kids were little, he would sit down and drink the two gallons of milk his wife had just bought with WIC coupons for his kids just so they couldn't have it. And that was one of his minor sins. His little girls have grown up to live extremely sad broken lives. They are in their 20s now, unmarried with multiple children, and involved with drug dealers, very abusive men, heavy drug use, etc....
Count your blessings and pray for God's protection for your little girl every day, multiple times a day. Pray that God will intervene in your ex's life and that if she will not change that she take herself out of her child's life. And love that little girl like there is no tomorrow and as if her life depends on it. It does.
