Hi Anastazie,
Welcome to this forum. That sounds like this is very troubling for you. Can I ask a few questions? Do you support your daughter while she is at school? If so, is it implied that you be involved in her life?
Are you more upset that she lied and he encouraged it (probably) or that she's dating this guy again?
If you can try to get to the root of why you feel upset it might help you communicate better with your husband. He may be willing to listen to you if you phrase it differently. For example, "I'm so Mad at her!" could be replaced with "I feel hurt she lied to us after everything we do for her." Perhaps then it could at least be a constructive conversation in your household instead of an argument?
My husband and I waste many many hours talking about his adult kids, and the subject of lying is one common theme. My stepdaughter (his adult daughter) lied to us about doing drugs. Not cool. We gave her money when she was doing the drugs that year. Also not cool. It took some time, and marriage counseling, but we are now able to talk about her just the two of us without arguing. It is possible one of the hardest things I've had to do in my life since it's his kid and I didn't raise her.
Enabling your child, whether they are 20 or 50 is probably not a great thing. Can you talk to your daughter about the lying and let her know the consequences. ie, it is a breach of trust and if she continues and hangs out with people who encourage that, you will without financial support. Or whatever feels appropriate. I'm just trying to understand if this boyfriend is maybe not the type of person you want your daughter around, so it's maybe a bigger question of his character?
I think it's OK to have conversations about loved ones about their behavior, their friends, when we are supporting them. If they are holding out an open palm every week and saying "hey, where's my cash?" that's fair game. You're probably investing a lot for her to go to college. There's expectations that she's taking it seriously and studying, not admiring a boy.
Is it time to maybe get her alone for coffee with Mom and have a heart to heart? Could you frame it in a loving way that maybe she would accept?
Not saying I can do this, I'm still pissed at my Kid!
I just kind of wished I'd approached it differently since now she doesn't talk to me at all anymore. She does allow my husband to pick up her two boys occasionally. Although, last weekend we tried to get them they were both "grounded" and as punishment she wouldn't let them see us. (my husband was not too happy with that, he said she was using it as a weapon and that is not right)
Just try to keep the big picture in mind is all I'm saying. She's your little girl, but she's growing up. She probably does need a little independence now and to "learn for her own mistakes" as Pook already mentioned.
I think back to High School and I'm pretty sure I never told my mom the truth about anything (especially not my boyfriends) from 15 on. Believe it or not I'm a pretty well adjusted adult, with no criminal record and I didn't married a thief or a liar. LOL
