My partner of 12 years has left me for the second time?

My partner of 12 years had left me for the second time, telling me all the same exact things as last year that he doesn’t love me anymore and there’s no future. He’s left our family home and 6 year old daughter. I know it’s foolish of me to want him to come back but I love him. He’s barely spoken to me anf just left. If he really doesn't love me, why is this the same pattern and words as last year when he did it? I’m so confused.

He was the one that came back to me after the 1st time! I haven’t drove him away well at least I thought I hadn’t, he said that we live like we have separate lives, yet I was always asking to do things together as a family.
