Three weeks after my wedding I discovered that my husband was cheating on me

Three weeks after my wedding I discovered that my husband was cheating on me. He had been cheating on me our entire 3 1/2 year relationship with Multiple women. He messaged one of them the day after our wedding arranging to meet up for sex! I’m too ashamed to leave him and for people to know our marriage has failed, but he’s become abusive, accusing me of playing victim. Like an idiot I’m still fighting for the marriage. I know I’m stupid for staying. I was so in love with him and it’s taking me time to process it all. I’m afraid of the backlash. Emotionally I dont know how to cope with it. I dont know what I’m looking for, just sharing my story on a sad evening.

Edit: wow I’m overwhelmed by the response. Thank you so much. I’ve taken two STD tests and thankfully I’m okay. I can’t get it annulled I looked into it.
