I dont know how to even write this

I was with a man for 6 years, we split because the relationship wasnt working, amongst other things. We have kids together and have been split for 4 years, we've always remained friends even when getting in new relationships. I split with the new partner a couple months ago, i obviously told my ex as it impacted the kids. His attitude changed towards me in a good way and then a few weeks ago he split with his girlfriend, since then he has basically declared how he has suppressed feelings he had for me this whole time and how he thought the new guy made me happier and even though it killed him to see me with someone else and that he was with someone new too, he just wanted me to be happy so didnt express how he felt... I love him and will always love him, and honestly we was so young when we was together I feel he has matured a crazy amount and I have too. Would you say it's worth seeing how it goes? Not as in jump into a relationship but see how things could be? Keeping it from the children and remaining our friendly selves in front of them? It seems crazy but honestly I feel like now it could work
