Hiya hope I can explain this properly.
I'm on UK holiday at the moment with my DC, just me and them. I have BF of approx 8 months (met my DC no red flags there).
Also get on well with ex, we co parent well, have DC 50/50, I'll pop over for a coffee on a Sunday very occasionally to see DC whilst in his care if I'm at a loose end.
Ex has suggested he come and stay for a night in the place I have booked (at no extra cost to anyone) as he will be in the area with work anyway. I have no issue with this, be nice for DC to see him, he can sleep in room with DC, it's a wooden lodge resort type thing, we will spend a day together then he will go.
Bit worried on how to tell my BF this last minute plan? Ex and I have always co parented well and have been separated 2.5yrs now. Am always complimented on our co parenting relationship. We hand over at nursery so don't really see eachother or are in eachothers pockets, communication is only about DC. Split when DC was too young to remember. He is 3 now.
If you were my BF would you be upset?
