Sexual assault

So I've been struggling a lot lately with the nightmares and memories of my sexual assault. This took place a few years ago when I was a minor with an ex boyfriend. This guy took my virginity and then dumped me over text message a week later. I was heartbroken bc I was blinded by the thought of having real love. Since then I have been dumped by an ex fiancé of four years ON our anniversary (that he forgot) over a text message. Left me with a mortgage and all the bills to pay by myself to go live back with his parents. (He had gotten himself into some serious debt that he hid from me). He told me he didn't love me anymore. And now I am again in a serious relationship. I am newly engaged to my current finance and he is the complete opposite of my exs. He is everything I want and more. I never have to wonder if he loves me or if he is hiding something from me. I feel like a treasure when he loves me. Back to the point, idk why I am going through this phase but ever since I got a good man in my life I have been struggling with the real ness of it. I believe the drastic change is doing something to me. I keep replaying in my head my assault and everything on social media and tv that resembles rape, woman shaming, even graphic sex scenes where there are naked woman had an effect on me. It's almost made me sexist in a way. My brain tells me often that all men are trash. But I'm not sexist. I am so in love with my fiancé now that I wouldn't trade him for the world. My main question to anyone who has gone through sexual assault is if therapy has helped anyone? How they got through the hard time? Any advice or kind words are greatly appreciated. Thanks!
