Try to make this short. 20yr old son living back home after 3 years away. Step dad ( my husband) and him never saw eye to eye. My son is in a relationship and has his girlfriend come over but my husband hates them having sex in our home. Its the 21st century and its one girl not different girls. There was some noisy sex which made us uncomfortable but since telling my son that has stopped. It has got to the point now where my husband is indirectly asking me to chose between my son staying or my husband leaving. Am i being unreasonable? Ive suggested she doesn't come over when just my husband is home in the afternoons. He says its disrespectful but im more relaxed about it. My husband suggested he leaves (during a drink induced argument) so i just said if was up to him. He hasnt spoken to me since. That was 2 days ago. Im not turning my back on my son he has no where else to go. My husband often says he can just leave whensver we have discussions and we dont agree. Just also to add ive slways felt guilty about leaving my childs father so have always trued my best to look after him. Advice please.
