Should I forewarn my adult daughter?

My daughter lives at a distance from us and we recently my husband and I went for a ten day visit. This young man who is mid thirties seems to be very much afraid of committment and they are living together for four years. She is suspicious of her boyfriend taking money from their joint account why she has that I dont know. They split things down apparently the middle. We went out to restaurants and during this time her boyfriend would be eyeing the waitresses and i found it to be rude and i didnt know how to handle it. At one restaurant two of the waitresses were falling all over themselves to get his attention. I found it degrading to my daughter who is very beautiful inside and out and loves him dearly. His father verbally abuses his wife and is known to cheat on his wife. He has a large ego and Jody seems to have the same ego. I am afraid if i tell her and afraid not to tell her..what is your opinion???

First ask your daughter if she wants to talk to you about her boyfriend. If she says yes, then ask if she wants to hear your thoughts about him. Let it be her decision. Don't force your opinions on her if she's not ready to hear them. If you do that, you will only push her away. Tell her that you are there for her the day she wants to talk about it. That way she knows you want to support her and won't feel criticized. Hopefully, you can have a constructive conversation that will help her deal with her situation. She might also need help taking care of her finances so that her boyfriend doesn't take advantage of her.
