*LONG RANT* & also really hurt.

Ok so my fiancée mother walked out in him when he was a child. About 2 years ago there got back into contact.. everything was going fine, wanted to be involved in our child life

anyway so we have a 9 month old daughter who she hasn’t once met,texted or rang to ask about her. I know we never let her see her after the hurt she has caused but I don’t understand how someone can be so cruel and not want to see their grandchildren. Sorry I just need to rant
