once you go through a certain number of marriage candidates, the only choice you have left is the oldie guy. no matter how many times you go through it, it will only give you him/her from that point forward.
Just keep coming back at random times and hopefully you will get another male tama. All of the oldies are the worst, and no one wants to marry them! I totally understand! ^_^
You only get 3 'normal characters' to come until the old guy comes. You get 3 choices of normal adult characters every day, so don't worry. New characters will come tomorrow.
lol thats funny i am very sorry about your misfortune in a partner thats gross lol oldie marrying a regular I though only oldies can marry oldies. anyways Yeah you get new choices everytday and I was under the impression that you don't marry oldies until your one yourself (I don't own one yet but I have been researching tama-gos trying to get ready so I know everything about it when I get it.
