I do feel for you not being able to see the DGC,but I have to say I agree with everyone else in saying ditch the bible verses?. I agree with those that said sending this comes across as manipulative, and to be honest a bit obsessive.
I also feel that you have not told us the whole story here, I cannot believe that you have no idea of the reason that you are excluded, as you also state that every other family member is not.
If you want genuinely informed advice you need to be a bit more explicit about the reason for the rift. It’s easy to vilify the DIL, but we are only hearing part of the story. Like you she is a mum so her focus will be on caring for and protecting her children.so far, unfortunately, you have not shown that you are a measured and stable addition to the family,with the unwanted visits, standing outside in the cold and random bible verses.
I am sorry if this sounds hard, and I really do feel for your hurt, but I think you need to take a step back and maybe examine your own actions and words, and see where that gets you. Maybe if you can show through other family that you have reflected and changed over time overtures might come your way.
