My husband was was married to his late wife more or less than 20 years but we never had problem wiht his past.I am the one who asked question about her but he never mention anything about his past and about financial matter I have never ask anything for my husband as I work and earn money.I know that she should tell anything to you about her family and not to wait tell you get married as it sound like your the bait.Why not apply for fiancee visa and see what happen then.I really wish for you both to settle this thing and may you be together inspite and despite of everything.
