My husband and I have been married for nearly 3 years and have and 3 year old son together. He has 2 other sons by 2 previous relationships. When we got together I owned a flat which I sold and with the proceeds bought a house for us all, solely in my name, though we have jointly contributed to the mortgage. Over the years we have been through turbulent times; namely a gambling problem on his part and a drink dependency that he is in denial about. Over the last 2 years he has frequently accused me of cheating, he has been through our bank statements for the last 6 years, logged into all my social media accounts (to see historic messages). I have modified my behaviour to avoid these accusations and to please him. But I have had enough.
I have suggested that we separate (even for a trial period). But he is refusing to leave. I haven't taken any actions such as packing bags, locking him out. But I don't know how to proceed. He wants me to move out as I made the suggestion. If I let this play out with him here I think he will worm his way back into my good books and all will be well for a while but then we will have another round of accusations in 3 months time.
He has said previously that I can't make him leave as he has the other two boys to think of but they have primary residence at their mothers - is this true?
What should I do?
