i have been with my partner 3 years and we just recently bought a house. we are both 28. we have no children and are not engaged. when i first met my OH he lived at home with his mum dad and sister. they didnt come across like a close family and he never said they were. his mum told me when i first met him how his sister didnt have many friends ( his sister is 30 this year). the sister started of polite but over the time they have all become out of control with the way they treat me. It started with the sister who was obviously jealous her brother had a gf, she was single and would do things like invite him to the gym when i was at his house ( which he went to, and left me in the house) ask him to go visit family but make him aware it was 'family' only so therefore i was not invited. His mum told him to not neglect her now he had a gf which i found odd, she was 27 when we met. now she has a partner and is even worse. We dont talk because i became sick of how i was treated, i could openly hear his mum and sister talk about me in the house. They would say to him im rude but i didnt feel like i had anything to say after i said hi because everytime i was in their company they would just talk about other people which i found draining.When we completed on our property nobody congratulated us, instead they ay things to him like are you sure you can afford to buy, and is it a bit soon. I never have taken money of my partner and earn more, yet he basically pays their mortgage in rent and is constantly giving them money.The mum wasnt ambitious with her career choice which is fine but blames it on having children ( even thought they are now 28 and 30) and i feel has a problem with the fact i carved out a good carer and encouraged her son to start his own successful business when they told him never to start his own business. it came to a head recently and i walked out their home with the intention of never returning. I have never been rude, never spoke about them to my partner- only told him when i found their behaviour unsettling. Now we have bought and moved ( it took him 3 months to even tell them we bought) i feel anxious about them coming to our home. They emotionally blackmail him, he gets texts saying how they will struggle without him and he should remember they were around before i was. I try not to talk about them as they are his family and he gets mad pretty quick when i do and says ive always had a problem with them, which isnt true i just realised very early on they couldnt accept their son being with someone who could potentially bring more to his life then what they offer. His mum trys to compete with presents etc and it makes me feel uncomfortable, im his gf not his mum, nor do i want to be.I feel like i was bullied for 3 years and dont know how to ever accept them.In the time i was with him i never took anything from their house,, i would even bring my own bread, yet they would eat my shopping or dinner even though i was only their once or twice a week.They have caused me alot of anxiety and i struggle to relate to people who talk about other people constantly and it always seems to be people who have made a success of their lives. I know they will have to visit but i dont know how to act, i havent seen them since i walked out of his house. i dont expect my partner to have a problem with them but there is lists of reasons i dislike them and im unsure how to move forward with my partner.some of the things he doesnt see as rude as hes been brought up around it but i am going to struggle being around them.
