Ex spent the weekend introducing the children to his new girlfriend who he has been with approximately 2-3 weeks.
Am I wrong for feeling this is way too soon for him to be introducing the children to his new girlfriend? My youngest got sent to the girlfriend's sister's house for a sleepover with the girlfriend's children on Saturday night so ex could spend time with his gf, although my eldest got to stay at his dad's. AIBU for my ex to prioritise the time he has with his children (which isn't very regular) over time with his new gf?
