I have known my boyfriend and his family for 20 years, his mum was a good friend of mine and guided me through some difficult teenage years, she is someone I love and respect.
We are both mid thirties, I have been married previously and have children, he hasn't had a relationship for 15 years prior to me. He lives with his parents, has a job and is a nice man. He is very close with his parents and sibling who is married with children but spends time most days at boyfriend and his parents house. He does suffer with poor mental health and has confided in me for many years about this. Our relationship is generally good but we have had a few wobbles as we have very different life experiences and responsibilities.
I am not close to my own parents, and neither was my ex husband, so this is where I'm unsure if I'm being unreasonable or not. Anything that I discuss with him, is relayed back to his parents, and frequently also his sibling and sometimes to his friends too including general chit chat but also any issues I'm having with my ex husband, my children, my personal health information. If we have a disagreement he also tells everyone. I have asked him not to discuss my personal information with people as I value my privacy, he said he understood and agreed he would not like it if I were to discuss his personal information with others. He has then told his mum, my friend, that I have asked him not to discuss me with her, and she has accused me of gaslighting him by requesting that.
For further context, I am very newly pregnant, unexpectedly as I have a coil fitted. An abortion isn't an option for me in this stage of my life but I do feel I need to make a decision about my relationship. He has expressed that he'd like to move in with me and my children prior to finding out I was pregnant, but says I live too far from his family, too far from his job (both are 30 mins away) and that he needs to use his mum's car for work as his own is unsuitable.
I am unsure if I'm being unreasonable in asking him to stop discussing me with his family as I do not have such a close relationship to my own family and it can feel unnerving to realise that conversations I considered to be private have been relayed to others.
