Dear Abby >> I am a single parent of two girls. My oldest, “Becca,” is 17. She has been dating this guy and, as soon as she graduates, plans to move in with him and two of his friends (another couple). What worries me is that their relationship is pretty toxic. They are always fighting. I have begged her not to move in with him, but she won’t budge.

Becca has some abandonment issues. Her mom left us when Becca was a baby, and my second wife was emotionally abusive to everyone before we divorced. I think this is why Becca refuses to see how bad her own relationship is.

How can I show Becca she is making a huge mistake? I don’t want her ending up stuck in a horrible relationship. I’m also worried about her getting pregnant right away because neither of them can control themselves. Please help.

Dear Dad >> After a year of fighting with her boyfriend, Becca may change her mind about moving in with him once she graduates. (One can only hope.) However, if she doesn’t, try to arrive at a compromise with her. Tell her you love her, and your door will always be open if she needs to come home.

Ask Becca if she would be willing to start using long-term (reversible) birth control, such as an IUD or contraceptive implant, to ensure she’s protected from an unplanned pregnancy, which could disrupt her life. Your family doctor can explain her options to her if she’s willing. (I’m crossing my fingers that she sees the wisdom.)
