A1,
I think you are doing a very good job of handling things, and that you are getting excellent advice here. Hopefully your IC will be good, and can help you begin to work through the emotional side of things.
What Bigger says about time being your greatest asset right now is exactly right. You have time to process everything. There are no textbook 'right' answers in these situations, because a lot depends on you, and how you feel once the initial shock and emotional turbulence has settled down. That takes time, and you should allow the process to run its course, in conjunction with your IC and any advice from here that is useful, because that is how your solution will develop and mature into something that feels right to you, and something that you can live with. You may well experience various mood swings and changing emotions, which people tend to refer to as 'the rollercoaster', but that is all part of the process.
The exercises suggested by Bigger would be good to try, and your IC may have others that can help you mentally and emotionally test-drive various options to see which 'fit' you, and which do not.
I also think that what Bigger and others suggest about you focusing on yourself and your process is very good advice. By all means check that your daughters are alright, and perhaps ask if they want to talk, but they are basically adults now, and they have every right to make up their own minds about what has happened. Similarly, I think you are very wise to remain neutral in terms of your advice to them about their relationship with your WW/their Mom. It is really something that they have to fix between themselves. Your focus needs to be on you.
I do think the holidays are a tough time when you are going through problems, but you will have your daughters with you, and one way you can add something positive would be to plan some nice activities for the three of you while you will be together. Perhaps you can involve the girls in that? People do love to plan nice things, and you would be surprised how it can lift your spirits. And it sounds like the girls are likely to be very supportive of you, so why not make this Christmas all about the love between you, which is a nice, positive thing to focus on.
It may be a 'different' Christmas, but that does not mean it will not be good. Enjoy being with the girls, and chat with them about how their lives are going, and what their hopes are for the future. It will actually be a great opportunity for the three of you to talk about things that maybe you haven't in the past. It sounds like you will be spending Christmas with two wonderful and supportive people, A1, so that's got to be a positive thing, hasn't it?
Whatever long-term conclusions you reach in regard to your WW, you will never be in an 'all is lost' situation, because you have those two wonderful young women in your life, with all of the love they have for you, and all of the love you have for them. As I said above, why not make this Christmas all about that? That would be a pleasant and positive thing, wouldn't it?
Our thoughts are with you, A1, and we are all wishing you the best.
