Did I mess up

r/

I’ve been in my current relationship for 8 months now, met her out of luck and since day 1 I’ve been in awe of her, she’s the kinda person that we think have stopped existing now. We did meet for the 1st irl, but our relationship started with long distance, she was just so easy to love she made me feel seen feel loved treated me with sm kindness and care and respect, she’s the only person that i easily opened up to shared all my feelings and overthinking, yes I’m a crazy overthinker I get anxious but she listens she never judged or made me feel like I’m the problem, she still encourages me to share everything with her and I do. So yeah I fell in love so easily, she’s the kinda person you never or rarely come across and if you find you don’t let go. We both fell for each other. We still are very much in love with each other. She still does the same as I said above. We’re respectful of each other and both of us apologize immediately if we do something wrong, no ego no waiting for the other person to make the move. She made me feel like I’m worthy of love and i love her with all my heart with everything I have, hoping she gets the best in everything
But yesterday she said she was sorry because she’s been hiding one thing from me, she started doing it just 2 days and she hid it because apparently at some point i had asked her not to do that though she still hasn’t told me what is it (and if I would have asked her not to do anything that purely out of concern and care) and she knows this, she’s still kinda young in terms of how real world works, she has very protective parents so she was under constant shield from the outer world but now that she has started living alone she sometimes is unable to make the right judgment when it comes to strangers so in this regards I would have refrained her from doing something. But since she has just told me that she’s hiding something not exactly what she’s hiding, she asked for atleast a week more before she tells me. Now all I’m left with is my overthinking brain to think of all the wrong things. I have this weird ache in my heart or lungs idk, I’m unable identify my feelings though definitely I’m distressed I don’t know what to do i can’t even talk to her about this as she asked me not to. I still love her a lot and I’m pretty sure she does too but I’m scared of losing her now, did I do something wrong what if she does this again because she’s unsure of telling what if someone else comes and says that they have no problem with what she’s doing and she starts thinking they understand her better. She loves me I’m sure of that, I can see that in her actions also she could have not told me about this at all
Please help guys, I don’t even know what I’m looking for here, I just want to love my baby forever and for her to love me be happy me with me and feel safe and understood with me.
My traits – i overthink I get anxious I’m clingy I over love, I might be needy

Tl/dr : I’m just in a very confused space right now, can someone who has been in similar situations or understands this advice me on what to do
