[idaho]

My daughter will be 18 next week, we are at our wits end as she is on her 2nd relationship with a man over 45 years of age. First one was abusive and she hates him now but thinks this new guy really loves her. We have tried everything for her to see reason but to no avail. Anyone got any advice or suggestions PLEASE!!

Our daughter will be 18 years old next week and is in her 2nd relationship with a man over 45 years of age. The first was abusive and she hates him now but is convinced she loves the 2nd guy. She has no interest in boys her own age. We are at our wits end as to what to do. We have tried talking,arguing and counselling all to no avail.She knows we love her deeply. It is also having a major impact on our 2 younger children. PLEASE help with any advice / suggestions at all!
