how dare u suggest that you are comitted to ur partner then lust after ur partners daughter? so what if the daughter is nearer your age? for you to even be tempted it just goes to show what a poor partner you are to your girlfriend/fiance. whats wrong with you? if the girl is attractive-just see it as that-and not entertain your 'temptation' feelings,and for yo to suggest that if you met the daughter first a relationship could have blossomed suggests you had ore than an accidental meeting upstairs. how would you know if a relationship could have blossomed? How do u know shes doing it on purpose or is it your horny mind thinking she is? Basically-you fancy your partners daughter-i wouldnt want to go out with some one like you. Your only redeeming factor is that you dont like the situation.
All you have to do is tell your partner-look, i appreciate that your daughyer has come to visit you, however i feel uncomfortable with her walking around in her underwear whilst i am in the house and i wont stand for it, as i am not her dad.Please ask your daughter to consider that i am in the house and to be more respectful. If the daughter has a problem-then she can find somewhere else to live, shes 19, an adult, not a child. And if you cant keep your eyes off her then i suggest you do the decent thing and move out-as that is rattish behaviour, no matter how much you love your partner. .
