Also everyone has past trauma/hurt that put our defenses up but part of falling in love is slowly stripping those defenses back. Your afraid of being rejected or of her seeing that you are not perfect and you don't want her to know that your family are not perfect but real love is when she knows everything and still loves you.
Do not be afraid to put it all out there. Part of healing and forgiving your family for past mistakes is letting it all out, processing it, coming to terms with it and getting her opinion on it. She may even be able to shed some light on why your family are like that.
My Bf's mum is quite cold and un-affectionate. She has a permanent frown on her face and complains a lot but he absolutely adores her as she was an excellent mother, always put them first, never let them down and they never went without. She struggled to make sure they always had the best clothes/food etc and she made a huge effort to create positive/happy memories and family days out even though his father could be a nightmare a lot of the time. He has so much respect for her and so do I because of all of that.
I used to find her difficult because I always felt like an outsider looking in as shes so unemotional but I understand her and don't hold that against her. And eventually she let me in-she talks to me about her childhood and her husband and the past with her kids etc and that makes me feel included and a part of their family which is nice.
You should try to do the same. Let her know everything and she can make up her own mind about it all.
