My parents haven’t met my kids for 4 years

My parents really loved my two kids (their grand children). They were not perfect, but still good grand parents.

However, we decided to change country to find a place to live (extremely hard in the country we lived in) and to educate ourselves to get out of a bad situation, for our kids sake.

When we told them they completely exploded and decided to never have any contact with me and my children again. Last time they saw them or talked with us was 4 years ago, and when my youngest just turned 1 year and my older one 2 years.

I know that they have hurt me throughout my life, many times, although, I still cry about this and feel deep sorrow...

Just wanted to vent...
