Partner’s ex wife arrived with gifts for their child’s birthday (his contact time) and ended up staying the night at the child’s request. Day out together arranged for the following day. Partner says he was unhappy about it but couldn’t say no.
They are amicable which is great but he seems to minimise how friendly they are. I feel the no choice part is not true, just said to make the situation easier to explain.
Part of me feels this is a nice thing to do - both parents are there for the birthday morning and it makes the child happy. Another part feels very uncomfortable and I’m unsure how/if to articulate it without being unreasonable.
What should I do?
