Been separated a while now, trying my best to co-parent! ExH moved his business from our family home location 150 miles away nearer to his parents-predictably he then also moved quite recently. I was clear on making sure the kids were introduced to the new home and surroundings softly (both have autism and can be difficult with change). Night one - as soon as my child got in the car it was announced someone else was going to join them on the 3 hour drive to stay at the new house. (Male colleague who he employs). I found out this morning and wasn’t best pleased. I know I can’t dictate who stays at his house or who the children meet but day one?! I should point out the house is barely furnished and he’s only just made beds up and has no sofa sorted Tv etc so all a bit up in the air anyway.. AIBU? oh and he has left the child (12) in the new house alone and now gone off to the new work unit .. really 🤔 I’m told I’m overreacting so thought I’d ask the wise MN community.
