Unfortunately the way Hollywood portrays the love conquers all story that is why you and your daughter believe it’s the way to go. Sadly it’s not the case and I wish it was for you and your family. Not you certainly can try that scenario but more then likely it will make him uneasy a run like when you chase a cat.
The correct thing to do is the exact opposite. You take the attitude of “oh you think you’ll be better off without me well then have it”. Then you go out a live an awesome life. The reality is most men are not happier divorced. Within a couple years he’ll look and realize he didn’t have it so bad and look back in your direction. Ultimately you’ll have final say in the matter.
As for full blown love it’s just not the case. It’s your brain looking for stability and it thinks you will get that stability back by getting your husband to confess his undying love for you. This is not the case and is just an illusion.
No that one way or another the pain will subside and you will be happy again.
