I need advice. I am newly wed to a wonderful man and I have a toddler of 3 from my previous marriage. My husband also has a son who is now 12. When we all met everything was fine. All changed until we got married an d my son and I moved in. his son only comes over school holidays. He is rude to me and to my son as well. I once heard him telling my toddler to stop calling his dad dad cos thats not your father. I told my husband that it is not a good idea that they share a room but he insisted stating that his son only comes around 4x a year and my son is always here. When his son arrived he started crying saying that this is his room and all the toys (baby toys which were his but he never used them in over 8 years) are his. Then his dad will say we all going to go out and he will say he only wants it to be the both of them. in the beginning my husband would give in but not anymore. His son sometimes does not even greet me and I dont even make the effort to greet because as growing up I was always taught to greet my elders. I cook for his son and take him where he wants yet he still is rude to me and my son. Now my son does not like being in the house when his son comes to visit as well. My husband still puts him off to sleep and once i even saw him feeding him juice from a glass. His son is rude to everyone in the house and only sometimes does my husband discipline him. When he does his son starts crying saying he misses him and he the only kid at school whose parents dont come for sports day etc. His mum has re-married and they have been divorced for 6 years now. When I walked into the house i greeted everyone an his son was the only one who didn't greet me and my son and my husband swore him to come and greet me. I am trying my best but his son is rude to me and my son and I really cannot stand him sometimes. His mum also started interfering and messaged my husband that her and her husband are having problems. my husband showed this to me. I got so mad and Said this is not acceptable. I messaged her to say she must not message my husband about her love life and she is to only message him regarding their son. My husband is 15 years older than me and gets so jealous when my sons dad comes to take him etc and sometimes ebven forbids me to talk to him etc. but that is petty and not the main issue. My husbands son is not a bad child. He has just been spoilt and whines constantly and manipulates his father. For a 12 years old he acts like a 7 year old compared to his other cousins who are 12/13. He even got jealous that his cousin who turned 13 had a cake and he didnt and was sulky the entire evening. He can be mean to my son and I am always on my guard when he is around. Please can i have advise.
