my mom is a whore... no joke... what should i do?

hello all. my first post here .

i've got to introduce myself and my problem, so this may come across as rambling but i really do have a point!

my name is taylor (more often called tay) and i'm 19 years old. i currently live at home and attend college at NYU (new york university). i lived in the dorms for a year (freshmen year only), but i hated it and missed having my own bathroom so i moved back home with my mom. my mom is a model trainer. she owns a modeling school here in new york and teaches kids from age 3 all the way to 25 to strut their stuff on the runway. she has been a beauty pageant coach for over 12 years, and when i did pageants (from when i was 7 till 16) she trained me. my mom was a former model in france (she was born and raised there and moved to america when she was 22. she was a high fashion model/supermodel in new york and that's when she met my dad. he was an aspiring musician (how cliche.... right) and was currently enrolled in college. he fell very hard for her, and the two of them eloped. they never got officially married till after i was born. it's kind of sad in a way because they weren't sure they were going to spend the rest of their lives together until i came along (i'm an only child). my dad decided to give up his music gig and go on to what he went to college for, which was business. he began working in new york as a realtor and ended up hitting the jack pot. my mom continued to model, but it was harder for her because she had me to take care of. anyway to make a long story short- she ended up splitting with my dad when i was 12 because she felt like she was being suffocated by his job b/c it required him to travel so much that he was never home and she had to give up her dream in order to take care of the family. she was never a woman to give up her dreams or sacrifice, so it was a hard blow when she had to once my dad started making it big. they were temporarily split for a while, but my dad ended up filing for divorce because my mom would verbally harass him because she was so fed up with the marriage yet she was too much of a coward to actually file for a divorce. i have my own theories. i do think she was a coward, but at the same time she wanted the luxury that she was allotted while being married to my dad, because he gave her everything she wanted. a sweet penthouse, a brand new jaguar, jewelry, top notch designer duds, and he helped fund her modeling school.

once my parents were officially divorced, my dad moved to california where he started up his own company. i didn't want to leave new york, so i ended up living with my mom. she would always complain about the men she dated afterwards, how they never measured up to my dad. i never understood her logic, because she complained that the marriage was based on nothing, yet she missed him so much. my dad is a very passive guy, who rarely speaks up for himself. he kind of let my mom walk all over him, which she did. he just wanted to be happy, and she wouldn't let him.

i began modeling when i was 6 and like i said before, i entered numerous beauty pagents. i always won but it was like my mom was giving me an ultimatum- either i win or i shame her by losing. my dad would always be there for moral support, but he never once told me that i HAD to win. i went every summer and stayed with my dad and i felt like all the pressure that was put on me throughout the year (being the perfect model, winning every pageant, getting perfect grades, always looking beautiful, etc.) was instantly taken off. my dad soon started dating another woman and she was the epitome of what i wanted in a mom. like my mom, she was gorgeous and intelligent, but she was also a good person. my mom had a heart of coal, and although she showered me with everything i wanted, she never once told me "i love you" or "good job" or even "i want what's best for you." it was more of- get this done... and do it right... OR ELSE.

some people may call it tough love, but i sure don't.

anyway, my mom started seeing a guy about 3 months ago. his name is adam and he's an agent. he's 39 (my mom is 38) and he's a very good looking and charming guy. however, recently what has happened has seriously disturbed me.

my boyfriend who i have been with for 6 months is everything you could want in a boy. he's a model who works with abercrombie and fitch, hollister, lacoste, ralph lauren, calvin klein, etc. he's very gorgeous, very smart, and very sweet. however, he can be extremely sleezy. like i said before, my mom is a very good looking woman. she's gorgeous, looks about 20 and has silicon implants that are quite huge, and guys adore. anyway, for the past month i have been sensing that something is going on between my boyfriend and mom. somedays when i'm at school i'll come home to my boyfriend at my house chatting up with my mom. he's fully dressed BUT my mom will be in some slutty lingerie. i'm not saying she dresses up for him, i'm saying they have been doing something and when i come home... they stop. it's sickening! what's worse is that when i was having sex with my boyfriend, he MOANED MY MOM'S NAME!

i've confronted him several times, asking him if he's had sex with her. he says no, but he says that it would "be nice to have both of you in bed with me". WTF.

i know for a fact that he's been hooking up with my mom. i don't know if it's sex, but i do know it's something.

what should i do??? i love him so much, and he's quite a good catch. ahh.
