No court is going to give either of them 100% custody, nor should it be suggested. She needs both of her parents. And he's unlikely to become CP in the BM-biased Family Court.

Personally, I think he should fight for 50/50 and accept that BM won't coparent, or take EOWE and don't bother trying to coparent. He's wasting his time if he's trying to get 100% custody and cut BM out entirely. He seems so frustrated with it all that EOWE makes more sense.

No one is going to give him or her full custody. No judge will deny child time with either parents just because grown ups can’t get along.

Your DH isn't any better of a parent than BM is. Their differences in poor parenting are just that - differences. They are BOTH failing SD, and it likely won't matter which parent she lives with because SD has the freedom to do whatever she wants.

You're right that nothing is going to change. Your DH is part of that problem, and it's a problem that won't be fixed with a CO.

So in a week he has gone from I will sign my rights away, to I should have my child full time.

It's ridiculous to think BM is going to call and tell him every little thing.  If she dealt with the kid cutting class, and it hasn't happened again, then there was no need for her to call him.

The fact that she did call him about the sex ed class and gave him an opportunity to share his opinion and be involved with the final decision speaks to her willingness to coparent.  

He really needs to be careful here.  BM may also  be ready to go to court armed with proof that speaks to his past behaviors (drinking, dropping the ball on meds when the kid was sick....)

Instead of trying to screw BM on court why not simply try to get as much time with his daughter as he can?   Just say I want 50/50 because I love my daughter and want to have a more active role in her life.

Why is it up to BM to inform your DH about SD skipping school? While it would be nice for her to do so, he should be involved with the school and able to find out for himself. Doesn't SD's school offer an online portal for such things?

Your DH is not going to get full custody unless BM dies. Neither of these parents would win a prize, and I hope you'll finally be able to disengage when you have your own child. Leave them to it (unless it affects you financially). And please, please persuade your DH to take a parenting class with you. It will put you both on the same page, and maybe some of it will stick this time. Otherwise, you're in for a very bumpy ride trying to raise your own child.

Where you can get your life destroyed,  Wher you could be in the newspapers, have a record for being investigated.  And you want her in your home to give her more time to make fake things up.  This kid should not be in your home until she gets real perfessional help. Like an MD. 

DH should see her outside your home in a public place. Where there people and camber so everything is on tape. I would be happy to never see this kid in my home ever again.  But since she a Kid. Only second thing I would do is let her back in after some time spent with a perfessional and they thinks it’s ok to do it 

It’s not BM job to inform dad when SD skipped school. Why isn’t he involved in SDs education? He can easily sign up to receive info from school and he does not need BM for that. All he needs is to care about his daughter. 

He will never get full custody as he isn’t involved in SDs life (she might be at your house a lot but he isn’t doing any parenting).

If he starts demanding, all he$$ will break lose, everything will come to the surface: substance abuse issues both pot and alcohol, leaving child home alone a lot while you two out partying, anger management issues, non involvement in her education, medical neglect etc etc No way no how he has any chance of full custody. And I doubt he’d get 50/50 either 

To answer your question, Can DH be CP?

NOPE not unless BM is sitting in the back of a paddy wagon in handcuffs. Being in the clinker means that BM can not physically care for your sd. NOWWWW if you have a bm who is trying to be slick she will call her mother or someone she knows who will take and keep your sd until she is bailed out of jail which of course her family did for her.

Dad would not even know the arrest occured.

Based on true stories I have heard.

My DH got primary physical custody when SD was 5, We were in a very momma friendly county.  She denied visitation and phone calls for approximately 6 months, so she was in contempt of court.  He never had full custody, but she lived in our home full time due to BM's mental problems.
