My 2 females are in love with my male (hanatchi) and he's in love with both of them. I want him to marry my memetchi female. What should I do? My tarakotchi is 5 and the other 2 are 4.
Your females are not old enough to mate yet. You have to wait till they are 5 or 6. When they are old enough you connect them to your Hanatchi and they will marry!
Connect your Hanatchi with the desired mate until they get married, once they are of age. Technically, you can 'choose' their partners when you connect with another Tamagotchi
