I've been with my OH for nearly 9 years. We have 3 DD's. he used to get on with my mum fine. Although she does sometimes have her own way / belief on disciplining the children and feels he is being too strict etc and can sometimes cause a little vibe but she doesn't take over but she may try and determine what the problem is and try and calm it all down. Over Xmas OH alcoholic friend was over one day and swearing in front of the children OH told him to please stop . He did for a few minutes then started again , I managed to get him out the house by making out we were going shopping. This friend has a tendency to hassle as he is very lonely , I can really see why , any way this particular day he must have rang my phone 5 times and I was getting very stressed and annoyed. My mum room it upon herself to tell him to stop ringing/coming over when he is drunk . Since then my OH has been very off with my mum. She then came over one day and he was upset the cat had claws his new chairs and he said the cat will have to stay outside to which my mum said you can't do that it's cruel , and you will be reported etc etc my OH took this literally , I took mum home and she didnt come to our house for around 3 months . Since then everytime she attempts to come and see the children my OH either makes no conversation with her or goes out to avoid her. Mum is picking up on this feels unwanted/awkward and leaves. We have all been invited for a holiday with my brother now I have to choose between my mum or OH as I know OH will refuse to go if mum goes. N.b I can't visit at her house as it is under renovation and not safe for the children.
