Your daughter is trying to separate herself from you and dad.
Do not assume those texts are from the boyfriend. I bet they are from her. In her mind she is trying to act mature in her communications with you, even though this whole mess is like a giant tantrum.
Your daughter is also trying to save face with her friends and their parents by saying you kicked her out.
Now keep in mind, IF you gave her the ultimatum of her "breaking up with him or you cannot live here any more", then in a way you made it clear she would have to choose, because you were not willing to find a solution or compromise.
Again, I am trusting he is really no good.
But I warn you, when you make her choose and she sees something different than you do, it makes it very hard for her to confide or trust you.
When my husband and I were dating, his family was not that thrilled. I was not the cute little quiet blonde they had envisioned. I am the Brown girl who spoke her mind. I never sat there quietly while they spoke about politics and religion. I had my own experiences and I was brought up to discuss these things openly. They were not in any way used to this.
When we announced we were going to get married, they told us they did not approve. We told them, we were not asking for their permission, we were informing them and had hoped they would attend.
They told us they would never support us. We told them we did not need their support and so we do not ask for their help. They now get their feelings hurt when we do not ask them to help us during tough times. But they set the tone from the beginning and we have learned their "Help" comes with strings attached.
This month we will have been married 33 years. and there is still a lot of tension.
I really, really encourage you all to go to family counseling. Then bring in the boyfriend later. You all need to learn how to communicate with each other as adults instead of parents and children.
Your daughter may have to experience what a bad relationship this is on her own. If you keep trying to protect her, she is not going to figure out things on her own,. And Maybe, he will surprise you in the long run.
You have to let her make her own mistakes. You just have to let go at some point. I know this is very, very hard. No one wants their children to have a broken heart. To make poor choices, but for some kids, this is the only way they can learn and then grow up.
I am sending you strength. TRY to keep the communications open, but also stand strong and make her be an adult. That means have her work for what she wants and needs. Make her come to you to ask in an adult way for help. She says she is an adult, have her prove it. She could really surprise you.
