Don't now wether just to be angry or just to cry.. Long rant.. 
My MIL and I have bad history, we got into a big argument and she pushed me, I forgave her cause I can't be doing with tension and arguments and upset, but ever since she's been texting her son (my partner) saying she thinks I've got a problem with her especially when she has our son, and whatever else that gets said behind my back, I know what there both like for slagging me off as it's happened a hell of a lot in the past, I moved 30 miles away from my family for him to start out our life and this is what I get? Even after forgiving her for physically hurting me she still has the cheek to text her son saying 'she's got a problem with me having my grandchild blah blah blah' no I ha bet!! I'm sat crying cause I'm sick to death of getting made out to be the bad one 😭😭
