Minds I, I am the father of 2 young ladies in their 30's,so I have already gone through what you are now experiencing. When my eldest daughter was 18, she was dating a guy that my whole family hated,as he was stupid. I bought my daughter a dildo and told her to use it instead of him. My sons, one of whom is 6'3" and 270 lbs,, took a different approach. They took my daughter aside and told her that if she married this creep, they would kill him and dispose of the body. She still has the dildo, but got rid of the boyfriend.
