I feel so guilty

I feel extremely guilty for letting another man grope on my thighs, boobs, ass, and vagina and groped on him, even though my ex and I aren’t together and he’s made it very clear he doesn’t want to be together with me. At first it was just a back rub bc I was so stressed about the situation and then everything else happened. My ex and this guy aren’t friends, but have mutual friends so they’re acquaintances, which is another reason I feel guilty all in itself. I didn’t kiss this dude and didn’t let him go beyond groping me. He wanted sex but I denied it because it takes a lot of trust out of me to do that with someone. And then I feel guilty about thinking of my ex partner while leading this guy on. Never again🤦🏼‍♀️
