My friend took advantage of me last year in April

Hello so last year in April me and my friend went out to get drinks at a bar we stayed till 1 or 2 clock in the morning we ended up taken a cab back to her house she gave me some shorts to change into since I didn’t bring anything she ended staying in the living room with me since I was super drunk her boyfriend snd little baby was sleeping in the room I lay on the couch all I could remember was her taking advantage of me while I wasn’t my self at all I couldn’t do anything because I was drunk I wasn’t my self at all like she ate me out it was very wrong in so many levels to do that when I am not sober or anything I remember the next morning when I woken up what she did to me I told her what she did it caused a big fight we stopped talking for a bit well we started talking again I thought maybe I was tripping or something then later on this year she started sending me screenshots of girls wanting to do things to her she actually replied back to them I came to realize I wasn’t tripping that night or overreacting she actually took advantage of me I remember till this day what she did to me on her couch how do I cop with this??? Or erase it from my mind??? It still hunts me till this day and makes me so sick it’s just been bothering me a lot guys I don’t know what to do. I am currently dating someone should i tell him about this or not???? It was just shitty what she did.
