He’s been charged, so it hasn’t been to court yet.
@Helpwithsocialservices There’s more holes in his story than Swiss cheese; but I appreciate deep down you either know that or won’t accept it.
To answer your question, no, there’s no way around this. If you have him back in the home, your child cannot be there. You need to follow the safeguarding measures social services have put into place, or you will be determined to be unable to put her first, and she will go into temporary foster care. This situation has created a conflict between him and her, and you have to choose, at least for the immediate future.
If he’s been charged, the CPS think there is a good prospect of conviction and it’s in the public interest to prosecute him. If he’s found guilty, social services will continue to have restrictions, although they may change. You can work with them, but you need to be putting her first, and everything needs to be through the lense of keeping her safe and happy - not about you, him, or your relationship. It’s exceedingly unlikely that he’ll be able to live with you both or have any unsupervised contact if he’s found guilty.
It’s not uncommon for your first reaction to this to be like yours is - it’s a mix of panic and hope. What he’s done has launched a grenade into your life. In time, though, the holes will become bigger and eventually, although it’s sad for your relationship, you’ll be able to see that his story doesn’t work out, and even if he didn’t request these images outright yet, he was hanging out somewhere he knew that type of image was acceptable and being shared - and there’s a decent chance that’s on the “dark web”, so he didn’t just accidentally end up there. The forensic evidence must show that he had intent, or he’d never be charged over one-off cache files. Unfortunately due to my job I have been an expert witness in a few relevant cases for this type of thing over the years.
Once you stop clinging to the hope that this will all blow over and start accepting the holes, it gets a bit easier to plan life without him. Which you will want to do. You might also want to talk to someone - it’s possible this will be covered in the local news, which might impact on you/your daughters friendships.
