What condition did Jack make for consenting to Cecily's marriage?

Lady Bracknell comes to Mr Worthing's house in the country. Here, she, realizes that Algernon, his nephew, is engaged with Cecily, Mr Worthing's ward. So, Lady Bracknell, after knowing about Cecily's amount of money, she decides to consent the marriage between her nephew and Cecily. But, things change when Mr Worthing tells, that, Cecily doesn't come of age until she is 35. As a consequence of that, Mr Worthing makes a condition, if Lady Bracknell consents the marriage of Gwendolen, her daughter, and Jack, Mr Worthing will consent the wedding of Algernon and Cecily. Finally, Lady Bracknell doesn't consent the marriage because, she thinks that Jack isn't a suitable husband. Although, at the end of the play, things change. Is this true? Another possible answer?
