Can a sim remarry a sim they divorced? Sims 3?

okey on sims 3 i got my girl sim Cleo to get Thornton wolff to divorce Morgana and marry Cleo, but now theres 8 ppl in my house so i wanna get rid of him. now him and Morgana's relationship is at the max point and they're boyfriend and girlfriend, but the option to get married wont appear? and the girl that broke them up are enemies with the both of them so i dont see why he doesnt wanna remarry. i dont really want to kick him out, i want him to remarry Morgana. He hates children so getting Morgana pregnant wont work. Please help! I have the new late night patch, if that makes a difference. Oh and they got divorced DAYS ago. its been like a 2 weeks their time. :/
