Boyfriend dumped me

I’m completely heartbroken. Boyfriend of 4 months (who I thought could be the one) dumped me yesterday. I have kids he doesn’t. He said we live two different lives and my life is too chaotic for him. (I’m 44 he is 40). He knew I had kids and was all in..in the beginning. He is an amazing man but said he won’t give me another chance because he doesn’t see it working out in the future.
