Gf left because of my kids

Looking for any thoughts, advice, venting I guess.

So yeah, finally separated a failed marriage over a year ago and after some dating around. Connected with a amazing woman through work. But I've got kids and she was always unsure about being with someone with kids.

We pushed through though and looked like we were for the long haul for a while. Holidays, trips great times. Completely fallen in love with her, met family the works. And now, 11 months in just before Xmas. She seemed a bit distant so we had a talk. She can't be with someone with kids. Over. In pain.

Edit. Thanks for the comments everyone. Some of them have really helped me reflect and all appreciated. Any more thoughts are welcomed.
