Do these statements constitute talaaq

I need some clarity as to whether the below statements are valid talaaq or not?

1. My husband asked me a question: "What will you do if I have to ask you for a divorce?"

2. When asked by my family if he wanted to leave me, he only nodded to confirm yes.

3. We signed a settlement agreement regarding the visitation rights of the children and maintenance. He now regrets everything and wants to reconcile.

Please advise if we can and the correct way to do so.
