If I had a 16 year old daughter at home I wouldn’t have a boyfriend living with us.
The woman I work with has 2 girls, 13 & 15. She also has a boyfriend (she’s 43, he’s 53). He only spends the night if they’re at their grandmom’s or church teen retreat or a friend’s for the night. And she says that he will not move in unless and until both girls are grown and gone. I really respect her for that, I know it would be easier at times to ‘have a man around’ and she could use the help financially to pay utilities, mortgage etc. But she’s firm on it and I tell her she’s right.
