need help 😞or just to vent.

My husband and I are (I think) going through divorce. Or at the very least a rough separation. Weve been together 7 years and have two toddlers together.

He left our house on Sunday and I haven’t heard from him since. I’ve tried calling just so the kids can see him and it’s not hard on them, and radio silence. This morning my youngest had an asthma attack and I called him…. No response.

My daughter turned to me finally this morning and said “daddy doesn’t care enough”.

What should or can I do? Am I overreacting by chasing him down for the sake of my children? Anyone been through similar?
