If it were me, I'd try to acquire a few more females. ( I usually like to start with "at least" 3 females to 1 male, (preferably more) to get a long lasting pair)
Just because you have a male and female, doesn't mean they are, or will be compatible enough to breed.
Most cichlids have elaborate physical courting rituals that help determine compatibility
It sounds like your female isn't ready at this point, and your male won't put up with it.
In nature incompatible mates are simple chased away.
Tanks, no matter what size, do not allow this (except with dividers)
