My co parent and I’s relationship has deteriorated over the last few months, it started off great we do 55/45 we would go out of our way to help each other out on days the other had work commitments and it was always agreed that we would ask the other parent before going to family ( due to to age of parents) however we are both seeing other people and the co parenting relationship has become strained.
Co parent doesn’t have enough leave to cover half terms now as he has used it all, he since posed a question how would I feel about his partner looking after our child, they live separately so I was taken aback this was even an option (they have been dating just under a year however they are old friends of many years) I have tried to express I would like to have our son in the first instance as this is what we agreed, however it feels as tho what we agreed isn’t in place anymore but he hasn’t ever communicated this. I expressed I wasn’t comfortable with it and if need to give it thought as he had dropped it on me during pickup when I was rushing to get out the door to make an appointment. On that same day I found out when our son mentioned he had spent some time one on one with his girlfriend without the dad, so really the decision was already made. We have been back and forward in messages and it’s at the point I understand if this is the way forward there’s nothing I can do about it, however I have a number of concerns I want to put to him and a little bit of clarification on a couple of things but the main issue is I know this girl has suffered very badly with an eating disorder and as a mum I am worried how this may affect her in caring for our child and want it to be acknowledged that this is a concern - Aibu to raise this as one of my concern?
