Looking for advice on what feels a unique but almost definitely is not position.
I have been with my OH for 2.5 years and he has a 10 yo son from a one night stand. He has been an exemplary father and pushed to see him despite his mother wanting him to have no involvement. She has a SO and three under three with him. SS spends every other weekend with us and two weeks in the summer, one at Christmas and one at Easter. I do not have any children.
To start, SS loved having me around as it was more fun and the house was cleaner (his words). We moved in together after a year and in the last six months, things are really starting to deteriorate. It has reached the stage where if I come into the room, he leaves and sulks and cries. DB then follows his to listen to how he hates me and wants things back to how they were. The difficulty I have is that I have pushed always for them to have time just the two of them. I earn significantly more and therefore have paid for them to do things just the two of them and all of our holidays. I am fully aware that he is a child and constantly tell myself that his upbringing is important but I am basically not involved.
My OH has never had a relationship with his mother so I don't feel this is the standard 'you are not my mother' or a strong desire for them to be together as he has never known that. He is also perfectly happy that his mother is with someone.
I do believe he has lead an incredibly spoilt existence with my OH, mainly due to the limited time they see each other but also the fact he is terrified of not belong allowed to see his son.
I have suggested him and I get counselling to help manage it but babe says I am not a parent and he wants to do it his way and if the child's mother finds out we are getting counselling, he will not be allowed to see him.
My main point now is I am 35 and my OH will not even kiss me goodbye in front of my SS. Therefore, marriage and extending our family is far from his mind.
I feel selfish and also maybe not good enough to have my own children if I cannot even sort this out.
I am at the point though where I am crying daily torn between walking away from the situation but also loving my OH too much.
Help!
