S.B.
What a shame that is that your dad is doing this. Life is way too short to behave this way. He is missing out on so much. Unfortunately if this is how he has been all of your life pretty much, I don't think much will change. You could try talking to him but I don't know what good that would do but then again, it could. At least you can get out what you feel. In the meantime, I would put up some boundaries between you and your father. Accept him for the way he is and don't expect what he is obviously unable to give. However, I would continue to reach out to the kids. Maybe try to do things just with your siblings to keep the relationship open with them. They do need you in their lives. Again, sorry that you are experiencing this with your father.
