Thank you for responding so quickly.
They currently see their dad a couple of times per month. He lives about an hour away by car, so they see him when I am able to take them there. I don't leave them alone with him, he has no home,no car, etc. I never bash him to our daughters. They love him and hold him in pretty high regard. However, he has hit what I believe most would think is rock bottom, yet he continues to drink and blame his problems on everyone else. Part of the no contact with the other woman stemmed from him leaving bruises on her 3 year old son, which he blamed on the 3 year old. I just don't have the time or patience for him anymore, and like I said, will only take them to see him when I can drive them and stay with them. It usually involves going out to lunch or something, then driving home. We usually pick him up at a neutral location, like a library or starbucks or something. They don't know that he is homeless.
