Work Drama

I seriously cannot take it anymore - see I work for two men - one is the president and one is the vice president of the company - and they are together as a couple as well. Well I love my boss the president - he is a great boss and I like what I do and I even think my co-workers are okay - I have been here for 5 years. But lately the vice-president - which I work under has been crossing the line and I do not know what to do about it - the first time he crossed the line - he started telling me about his love life and I went to the president of the company and told him that I wanted to keep everything professional in the office and that I was very uncomfortable with that kind of talk - and everything was fine for awhile - then vice-president has been acting really odd lately and this morning it came to a head - see only me and vice-president are here in the mornings - I get in at 8 am and most people do not come in until 9 am - so vice-president tell me he would like to speak to me in the conference room - so I am figuring it is something work related - nope. As soon as I get in there he begins to sob like a big baby - telling me how horrible his life is - blah, blah, blah - so I told him I was not comfortable and asked to go back to my desk and do my work - which I did - but now I am wondering if I should tell president about this incident. I doubt anything will happen to vice-president being that they are a couple - and it may just make me look bad - so I am in kind of a crossroad here of what I should do - but this behavior is very unprofessional and I am so tired of dealing with it.
