OK.
Now this is a bit of Devil's Advocacy but you say that you are happy with the timescales etc.
If you look at the situation objectively, how does it look then? Through eyes not clouded by abuse.
Tbh, it's irrelevant really, you say your daughter is well provided for which is important and, I presume, she is happy? You can't go back and undo any of your decisions as there is another child involved now.
And people who don't know you - well your decisions and choices have no impact on them! Except for your partner's family because they care about him.
What I will say is that I use to work in CP and have a lot of contact with children through work who are on the CP register etc. None of the parents ever agree that their decisions are harmful to their child. Many of those parents are also living with trauma so they just don't see it.
If you are truly happy and truly believe that there is no reason for others to judge you negatively beyond their own prejudices then there is nothing to worry about.
If there's any part of you that thinks your decisions are trauma informed then I would urge you to seek therapy for them. Just so that life going forwards is as good as it can be for you and your children.
I'm also saying this from a position of being able to look back on my life (I'm 49 and my children are now adults) and I can see that some of my decisions were trauma informed. Not around relationships (unless you consider being single for 10 years to he a trauma response- which, actually, I do! So scrap that!) but in terms of other big decisions I have made (and continue to make) but mostly I'm OK now.
I've found a way to live with trauma and I use people I know care about me (and MN under different guises) to reality check myself at times.
But I'm not going to say there's never been an issue.
My kids have turned out OK though 👍🏻
