@exhausted ,
Well, if it helps:
- I don't know any separated couple, where the mother lets the father see their child every single day (I'm sure there are, but I don't know of any)
- I agree that would make moving on very difficult, and finding a new partner very difficult
- I also think that the time consumption of such an arrangement would be excessively exhausting (over & above that of raising a baby), when compared to normal arrangements for child visitation
On the flip side, it's great that he wants to be involved in his child's life so much - he could quite easily also have been a deadbeat dad.
Talk to him. See if you can find a happy medium.
