Ex h has newish gf ie it's on and off alot with whom he also has a newborn baby. Today, exh, new gf, their one month old baby, her 2 year old DC and my 4 yo DC went to a theme park about an hour's drive on motor ways away. When he dropped her back I realised she - my 4 yo dd- had been in the front seat the whole time with new girlfriend in the back with her two dds!!! I felt so upset that my DD had been put in the front, air bags still on. Aibu???
