So sorry about this, Suzy. I know it's not the way you wanted things to be.
I'm not sure your X was totally in the wrong though. Maybe he just felt you should have consulted him about the dates and such since weekends seemed to be your main time with him. Yunno, just ask him, "Would you mind if I did this with my GC on that date or would the other date be better?" or "Is there anything you were thinking we could do on this date? If not, then I'm doing this with DD and my grands. Want to come along?" If there was only one available date to do something like take the kids to see Santa, maybe you could at least have said, "This is the only day I can take them, but let's you and I do something special the next Sunday, just the two of us."
But I get the feeling you didn't want to. Probably didn't want to take the chance he'd say, "Please do it 2 weeks from now" or "Let's all do this instead" or "Let their mom take them to see Santa, that's HER job!" You say you feel bad about the kids having another man walk out of their lives, but clearly, not enough to have tried to compromise with him.
But maybe that's ok. Cuz if this man really meant something to you, I think you would have found a way to meet him in the middle. Maybe I'm wrong, but I don't think he did. It may have been nice to have a sort of partner for a while. But at this point in your life, he's just, yunno, a "headache" and you don't need him, IMO.
And breaking up with you by text? IMO, that's inexcusable! I wouldn't take him back on that basis alone!
Ultimately, I don't think the two of you are suited. I'm sorry that the kids have "lost" their "granddad" but, overall, it's probably best for everyone that he's out of the picture.
And I agree with the poster who said to be careful from now on, who you let be established as "Granddad."
