I am sorry that this feels bad for you just now.
I do not think it is disloyalty really. If you had found a new partner, then he would have become grandpa 2 or whatever in the eyes of the GC. I know it feels like a pain, but that is probably because you are still hurting from the break-up, so this happening has a greater significance to you than it need.
I cannot imagine that anyone has let this deliberately happen to hurt you; but it feels hurtful to you. Don't let this weaken or muddy your relationships with your children - that would be a double whammy, and you can do without that.
Please try and enjoy making a good relationship with the lovely GC, regardless of what they call you. The love is no less, never mind the name. 
Ladies would you post on a predominantly male forum on a sexual matter?
