I've been thinking about you and your DD more whilst walking my dog this afternoon.
You obviously care and want to change and have the beginning of some insight into your behaviour and upbringing, and I would give anything for my mother to come even close to this point.
I am not a counsellor or psycologist, so this is all just from my own experience/ reading.
I think that you need to accept that you do not have a maternal bond with your DD and that that ship has now well and truely sailed. There is no way you can recreated that window of opportunity in early childhood to form it, and you need to grieve that and so does she, and this is really hard and really painful, I've been through it from your DD perspective and it is horrible, and I do still get pissed off with unhelpful comments on estrangement threads, and in real life, on here where people who clearly are greiving much loved mothers wade in with - "one day they will be gone" - yes they will and I still will have never experience that maternal bond - it sucks!! And i get sad at christmas.
You need to think about what non- romantic relationships (friendships/ extended family) you would hope for your DD to have to guide and support her through life as a teen, young adult, new mum, etc, and then you need to become that person to her.
So if you think it would be really great for her to have someone practical, non-judgemental and knowledgable to help her navigate the complexities of adult life like house conveyancing then be that person for her.
If you would like her to know she always has a free roof over her head to escape to without judgement if she ever finds herself in an abusive relationship, be that free roof (I have a friend with money and an annex which has had various waifs and strays in it over the years as and when required, I've never needed it but knowing it was there is a big deal).
If you would like her to have someone who sticks on overalls and helps scrub and paint her new home - be that person.
If you want her to have a friend who looks for the subtle signs that something is not right and gives her the space and opening to talk about it - be that person.
If you would like her to have someone she can trust with her children when she has them - then be that person, which is going to take a lot more work to achieve, but might be your end goal.
There are ways of having a positive meaningful relationship with her without the maternal bond, I love my closest friends I don't have a bond with them in any close family or romantic sense but they are still super important long lasting relationships. The best you can hope for now is to become an incredible life long friend to your DD, you can not create a maternal bond that should have develop when she was a baby and young child, now that she is 13. It just won't happen and trying to force it will make the situation a million times worse.
