Lord almighty, for the life of me I'm astounded time and again that a parent could abuse their own child (incest) and yet, I know it happens. Saying I'm sorry for your pain is such a small measure to how you must feel. I'm sure there will be others here who can support you in a more concrete way. I guess my first thought would be to find a therapist for yourself. Then, does your daughter want to remain pregnant or is this an option for her given how far along she is and given the burden on her and on you bringing a child into this world under those conditions. Drugs affect the development of the baby prior to birth. What a tragedy for you both. Your former husband took the easy way out.
