After betta breeding quEstion!?

After my male and female veiltail betta spawned, does the male have to be with the eggs in the styrofoam cup and bubblenest if no other fish has acces to the eggs? So basically my question is- can I move my male betta back to his 5 gal tank and my female back to her side ofthe 10 gal tank (their is a divider that the me male was on with the eggs and the female on the other? And my bettas are taking like hours to mate, and everytime they rap up like either no eggs or very little come out. Is this normal, ik for a fact my female isn't inexperienced and I do believ my male is experience in breeding As well, y aren't they just doing it quick like all the other times
