Much of what you all have said is true. Just frustration on our parts. We have tried everything that we could think of. The last time that my wife called to talk to the girls, one is 12 and the other is 18 but has downs, the 12 year old told her not call anymore because it was harassment. She did not come out with that, we think that she was told to say that by her lesbian mother, the lesbian that lives with her or the girls lawyer. Up until her mother got the girls about a year ago we had a very good relationship with the girls.
I can not get past the lesbian relationship. I graduated from high school in 1958, before everyone in our country started teaching the "except everyone no matter what they are or do". I am old. I grew up with values and standards.
You are right we all share the blame for the disaster in our family. I could have said more when I saw how she was acting with young boys. But her and my son had been married for 10 or 12 years and I would have been accused of interfering, was told that I was and laughed at for my "old" ideas.
My son was not a strong enough father figure, she "wore the pants" as the new wife does and more so.
A twelve year old could indeed come out with that on her own. Whether she did or not it is up to you to talk to her mother and negotiate visits or call times. If your heard 'don't call back it is harassment' only from the child... Talk to the mother. The child is not the one in charge.
Be respectful even to those who do not live according to the standards you subscribe to...even when they do not deserve that respect by your reckoning. That is in itself an old fashioned value that will serve you well here.
I hope you are able to make peace with their mother and her partner so you can have a healthy relationship with the children. Stranger things than 'getting past the lesbian relationship' have happened.
Talk to the mother about it and ask to meet with her and her partner without the kids. Tell them..."I am old. There is more than enough blame to go around for everything that has happened and I am sorry. I'd like to still get to have a relationship with the girls while you're raising them."
Ask them how you can interact with the children. What needs to happen for them to be comfortable with you coming to visit and then do those things that the mom suggests.
Make the kids a scrapbook of neutral/positive pictures of
themselves maybe from before all the trouble. Be willing to make a scrapbook of them now in their new home with their mom and 'the lesbian' included in the theme. Start thinking of them as human beings not strange others who are fit only for your disgust. The kids don't need anymore negative of any kind.
Be willing to just listen to the kids and to build the kids up without mentioning yourself, 'the lesbians', their father/step monster, or anything negative. Be there to hear them, not to fill them with your ideas and your wants.
Stranger things have happened than learning to adapt to what you have been given. If you are an old school praying man. Start there. The only things you may be able to change in this situation is your heart. Start there, seriously. The pain of terrible things can pass and make room for unexpected happiness. Prepare yourselves for that.
Best Wishes to You and your Wife.
