My 33 year old daughter wants to adopt a child and be a single parent instead of getting married and having a baby. How do I convince her to go my way? Tried and tested everything. ..any parents facing same problem as me?

Isn't a 33-year-old grown up enough to make her own decisions? If she wants to adopt and remain a single parent why do you have a problem? She is a mature adult, has her own wishes and desires, let her fulfill those. Not every person is meant for marriage. Nowadays single parenthood is not a taboo anymore. You should be proud of her.
