Sigh.
I truly do understand. My two sons and their wives also have a combined 5 children. They are growing up without me, but with plenty of other grandparents and step grandparents. It is not me that prevents this, but them. A few years ago they "disowned" me until I "can quit being disabled and be a witness for Christ" certainly not the Spirit they were raised with, but evidence of how much trouble I am for them and their faith.
My T assures me that my grandchildren know I am here, even though I have not even met one of them and not held 3 of them, ever. It is a good thing that they have so many relatives in their lives, but when they are able, will come seeking their other "real" grandmother.
We cannot force ourselves into their lives. It's depressing because I taught both my sons to go and visit their grandmother, not have her come to them, and usually took them, even when we lived 1000 miles away-- twice a year visits. (And my sons have lived within minutes of me, with no contact.)Now one is military and moves all around the world, yet he can never drop by heheheh The other is "too" busy with work, the children's school and activities.
You are at least able to talk to them, send them cards and maybe gifts? My calls aren't returned, but the cards and gifts are.
Recently my closest living, and older son called and invited me to Christmas program at his church, and dinner. Yippee! No, it was just him.. his family never showed their faces. I cried all the way home, and got "lost" due to the stress. Hang in there, luv ya.
As for that signature you have? Nice, but I always figured there was just an entire waste of extra glass!
