Idk anymore..

My husband and I have been together for 10 years but one year married. Well for our first anniversary we we on a tram up a mountain, hiked a bit , went to dinner it was a great time .. however when we got to our hotel we started drinking which at first was fun we went in the hot tub just enjoyed each other's company. Till I made a joke about some chicken we knew and he replied with no no I dont find that woman attractive lol but that little blonde housekeeper that I would F*ck ... I was so shook she was so tiny opposite of my husbands type idk it really took me by surprise... well I got offended and asked how often he thinks of sleeping woth other women he told me all the time and that he wants to get his own apartment and sleep with whoever he wants.. and went on to bring up his ex and how they met some of his sexual desires but I don't... do I have a right to be hurt and upset ?? I mean Im contemplating separation.. it has been an on going argument since the 26th about how he does think about other women and how its normal or not or how he just wants to have sex all the time every 4 hours and most days I dont want to so that's when he thinks of other women ... idk im so hurt I have really been working on myself and loving myself I lost 55 pounds and I feel amazing beautiful and he just killed it. What do I do... is it normal to think of other women ?
