This is making me really sad

I love love love my daughter and my fiance but we haven't had any alone time for a long time. he has other things he does like for example, his mom has him to do everything for her. And he runs to do it because he dont want to regret not doing it if she cant do it herself and something bad happens. He has 8 brothers and sisters. She only calls him to do things because she trust him the most. But he has a family now. He has a baby and we are to be married soon and its still the same as if his life isnt changing. Every morning, all day, she calls and ask him to do things. Even if we are out. I am marrying his family too and i get that. So i sit back and not say anything because i dont want him to be stressed out in having to choose. She is older and wont change her ways. Its just our family should be her reason to let him be. Ask your other kids to do things... And I WANT TO GO ON A DATE DAMMIT!!!
