Looking for help on how to manage a relationship with partners son. There has been no relationship between him and his son for over two years due to his mam cutting him out and stopping him seeing the son. However over the last 6 months he’s started seeing him again and for me it’s all for the wrong reasons and he does also agree. It’s can I have, I need, I want, will you give me, will you take me. Currently pays over the amount of cm and still expected to give and give. The son Is a liar, manipulator and rates himself as a “gangster”. When I first initially met him I was gobsmacked at his behaviour, his actions and did not want him around my son. Over the months I just don’t like anything I hear about him, conversation about him enrages me. His actions are just not what I like in a person and although he is my sons partner I can’t have him in my house and when partner wants to spend time with him I instantly feel angry and defensive. I understand it’s his son and no doubt people will say that’s just how it is but if anything is going to break us it’s his son.
