What constitues domestic partner ? What are the staute of limiations for prosecuting ...how?

I was violated by my older, more experienced, larger boyfriend after a night of drinking when he abandoned-neglected me adn then he ried to show off to his friends his domination and control over my emotions, by holding me down and subdueing me whiel i was screaming adn spitting on him. He then continued to molest me adn come at me int he elevator all the way back to the timeshare, he molested me even though i asked him to stop int he room until he d me, when i gave up fighting from frustration adn weaness becuase i was crying so intensely....my boyfreinds friends was int he elevator adn the room the whole time it happend, adn was giggling adn making jokes at my weakness adn helplessness while my boyfriedn violated me , they friend of m boyfreidn did nothing but continued to laugh and snicker....this was over five years ago,,, adn i never reported it, becuase i forgave my boyfriend.......... I never considered this to be a crime, beucae the violation wasnt violent adn wasnt forced, but i was so emotionally weak and hopeless at the time that i was very defenseless physically. HAs a crime ben committed? Was it that happened to me? This was the worst experience in my life with that boyfriend when he wouldnt respect me in front of his friedns even thoug i was crying hysterically,, adn still he continued to do as he pleased. What should be done about this....i have been intherapy for five years beacuse of this and other emotioanly abusive portion of that log term aul realtiosnhip. Shoul he be charged? Has a crime occurred?
