Blended families are difficult to deal with sometimes. I commend you on keeping cool and doing what you feel you need to do by seeing your dad and his g/f.
Two people can go through exactly the same experience and bring out of it totally different views and feelings. Since you are both different people....I think that makes sense don't you?
Maybe you can find some time during the holiday's to spend with your dad away from your sis's home? If she isn't going to invite them to her home for the holidays, there isn't much you can do about that. It's her home eh?
It sounds like your sis has some anger issues that she's having a tough time dealing with. I'm sorry about that. But it doesn't mean that you have to take on her feelings. You can validate her feelings by saying to her that she has a right to feel whatever she wants, but that you too have a right to feel what you feel. Validating doesn't mean you have to agree with her....just that you give her acceptance of how she feels. Maybe by doing that, she will be able to learn to give you the same in return?
I know it's hard to keep family together when there are rifts. And I'm sorry you are going through this. Just remember that you have every right to see your dad and have a relationship with him, even if your sis doesn't understand why. I wish your sis could let go too.....but she has to be the one to want to make the change.
I agree with you.....it's not worth spending all that energy on being upset and holding grudges. I would much rather spend that energy on good and positive things too!
I wish you and your family well saluki. I hope you can find a balance for yourself through the holidays.
