My boyfriend of three years has a "headache" whenever I want to have sex. Last night he got drunk at a work function and he and his colleagues talked about visiting strip clubs. He told me about it, so I told him that if he went, I would leave as I do not see that being something people in a three-year monogamous relationship should be spending their time and money on. He then went anyway. He checks my phone and is insanely jealous, so why does he think different rules count for him? Should I take this personally?
