Marrying when there is a need

Q: Is legal love marriage allowed which means without looking talking exposing one another. I (happen to be a pious unmarried male of 28) got information from a brother of a very reputed pious divorced women of 30 that she wants to marry me and if I do not marry her she will remain unmarried but my family will accept it for many reasons. She also said that if my family will not accept it then I will have to marry her secretly then she will remain in her house and I will remain in my house. And Allah made me too generous that I do not want to hurt anyones feelings so naturally I am also feeling love for her. So what should I do now?
