DD struggling with separation/me leaving soon and new relationship

[definitelymaybe8]

DD is 24 at home atm full time student
DH and I seperated about 7 weeks ago, initially DD told me to leave DH a few years ago and last Christmas told us we were living lie which we were sexless marriage for 11 years.
Anyway I have a new love interest, she was keen to know and wanted me to share and being close to her did, so she kows I am occasioally dating. Now she is saying she doesn't like lying to her Dad and I said I wouldn't tell her any more if I see him, then she says she needs to know when and where I am for my safety. Which she really doesn't...
Although I am seperated I am still in the family home for a few more weeks.
We have never fought like this before, I am thinking it's the fact I am leaving even though she is an adult and she is angry because she has all of my attention before today being an only child and her life will soon change even though I was losing respect for not dealing with a flatlined marriage.
I need to have some happiness and grab what I can, is this so wrong of me?

7 weeks is nothing and probably makes her feel uncomfortable knowing. You need to move out before you move on.

Do you have somewhere lined up to move in to? Is she staying in the family home with her dad?

As she said she thought you should leave I can see why you’ve felt able to be honest with her. But the realities of her parents splitting up and her mum moving on is likely to be different to how she’d expected it to be.

She’s 24. She’s an adult. She doesn’t have a right to dictate to you in your own home. But if she’s staying and you’re going it’s a confusing picture. You have every right to date and of course you don’t have to tell her your plans. Especially when she’s disapproving of them! But you’re all still finding your feet and I’d keep things on a need to know to avoid conflict and I’d be moving out ASAP. If you and your husband have mutually agreed it’s over, why don’t you tell him you’re seeing someone so she doesn’t feel she’s lying to her dad by omission?

Maybe the reasons she’s given are her actual reasons. She is old enough to know it’s sensible to let someone else know about your dates in case one turns out to be psycho. But she does not like keeping secrets from her dad and shouldn’t have to.

Maybe she’s just worried about you.

Why don’t you try making sure she knows somebody will know where you are and who you’re with and see if that helps.

We mutually agreed yes however I can't see him taking kindly to me starting another relationship, in fact he'd hit the roof despite him not wanting me and living a lie for years. He would make it very hard for me financially too.
I can't move yet, I'm moving back to my inherited property which is currently tenanted.
It's taken me many years to be this brave, come this far and the new relationship was just the touchpaper..
For once I need to be selfish which is alien to me. I have lost my parents and brother and I feel life is too short, I have to grab this whilst I still can.
I think I can't share with her any longer she can't know even though she wants to, but I get the third degree every time I go out or being messaged are you with him.
