What should I do if I like her mother more than her?

When meeting the family members of a friend that is your age or close to it, you may see similarities in both appearance and behavior. Therefore, your attraction may also be for the mother as well as for her daughter. Usually, you will meet the daughter first. If you have become close with a girl and then meet her mother later, you will most likely need to refrain from having a relationship with the mother. Problems will arise.

The only reason to establish a relationship with the mother is if the daughter is okay with you having a relationship with her mother, which she probably won’t. However, there are times where the daughter may move on to someone else and then won’t care who her mother dates, but that is very unlikely.
