Please, answer me... 😢😢😶😶

My hero, the man that has given everything he possibly can to me & my brother and who raised us as a single parent from toddlers has now been changed forever for me.

I have not had an ideal life from the start... having a drug addict/selling mother, her being put in jail for that (haven't seen her since I was 7), being molested and raped by several men throughout my childhood, at 16 actually developing a relation with one of the abusers that happened to be my aunts husband and had very bad depression from all of the mess mentioned above until last year I learned to control myself emotionally a bit better. And now this... (Photo attached)

After I made my husbands lunch this early morning and he left for work I see this FB message from my older sisters husband, which I have been in contact with recently rather than her because she doesn't have custody of her 4 kids and relapses with drugs. I stared at this screen in the dark for more of 10 minutes in shock, started to cry and had to calm myself because my 3 year old daughter is sleeping next to me. Mind you she doesn't want to contact me for the last 3+ years and the first thing she writes me is this.

How do I see my father after this? How should I ask him? What now?...

He has never since I have use of memory tried to touch me or my brother inappropriately, never. And I don't trust my daughter to no man other than my husband because the devil is the devil and as much as I love my family, just no + my sister and us have the same mom, different fathers.

Being a hopeful hippie that I am and trying to see/trust the best in people, I have feeling few can change for the better. Yet I am confused on writhing that last sentence because all the shit I went through as a child.

What now...
