No-one can erase the past, no-one can change it either. Those mlcer have a past with us, a long one. They can re-write as much as they like, it doesn't change a thing.
The past has a funny way of catching up with people. Just wait and see.
In fact, they are where they are because the past they had before us has caught with them and they felt they had to do something drastic to make it go away.They went away instead.
To start anew.They couldn't see any other way.
So what do you think will happen when their past with us catches up with them and they finally realise that running away was not the answer?
How do you think they are going to feel about us obs when they realise we carried on loving them no matter what they threw at us?
They will then realise that we love them for them, we know them better than anyone else does, we knew them before the lies they live and we believe in them still.
That is when they will realise that they will never have that again if they don't pull their finger out.
As we will stand there, strong, renewed, loving still, non-needy, bitterness free, independent and fun again, we will be an attractive force to them. One they will crave and want.
People always want what they can't have, and that's when the spark ignites again.
Just my opinion, of course.
