Posting this separate after my comment became so long…
I’m having a general panic that my 15 year old daughter does not need me at all and I do not factor into her life whatsoever. Try to speak to her and she teases me and brushes me off. Her girlfriend wrote my wife a lovely note how she and my son are so lucky to have a mother who cares about them so much. No mention or even nod to the fact that I exist. We parent as a team…the way she is raised and all of the love and support she gets is 50/50 in my opinion, although my wife has the direct conversations about relationships, sex, girl stuff because she doesn’t want to talk to me about that.
I suffered emotionally as a kid/teen and I have fought to get her therapy and medication, she went from being anxious beyond belief with suicidal ideation to pretty fucking happy nowadays…and that’s because I fought for that, based on my experience. I’ve given her the support I wish I had.
Anyway, I hope it’s just a phase and she will talk to me again someday without giggling like I’m just a weirdo. I know what it’s like to be a teenager, I have a lot of wisdom. I love the shit out of her. I hope it passes and we are super close again at some point.
I would relax. This is late teenage years. She's becoming independant so she can set up her own life. Once she's left the house and gotten established, you will probably reconnect and have a deeper more adult relationship. Just keep telling her you love her and you're there for her and keep asking her about her life and what's happening.
