I think i sexually assaulted my ex

I think i sexually assaulted my ex... I had a relationship with my ex when I was 17-18M, and the relationship was a toxic one that lasted a year. In hindsight, both of us weren't stable and we definitely weren't compatible with a lot of differing life values.

Recently, i remembered a few scenarios where I ignored her discomfort in sexual scenarios. We never had sex, but we did heavy petting in public frequently. Initially, she was ok with it, but as time went on, i think she became more uncomfortable as i became riskier. She never reacted badly when i was doing these things but she did express her discomfort after the incidents. However, I was too absorbed in my libido and for some reason thought that she liked me being rough since she said she liked 'bad boys', so I didnt really process what she said. It's not an excuse, and its so ######6 immature and stupid. I think i only realised how bad it was after she yelped loudly when i made a move on her in the elevator. After that incident, i realised how uncomfortable i was making her and i stopped initiating and doing all these things. I know this is not a valid excuse, and i dont want to minimise what i did, but i swear that i would have stopped it completely if i recognized what i was doing earlier. There were other occasions where she said she didnt want to, and i didnt do anything.

I feel really guilty for the way i treated her. I loved her but i treated her nothing like the way she deserves. Looking back, it was so clear how uncomfortable she felt, but i ignored all the signs. Im really ashamed of myself for being driven by my libido and I am planning to see therapy as well as address my porn addiction. Did i sexually assault my ex?

I think your doing the right thing by questioning yourself over this

I can't answer your question but if you think you crossed a line in some way and you are seeking help for that then surely that's a step in the right direction

I've been in relationships where I wasn't aware I had been abusive until after I'd grown up a bit

If you can move forward and be a better person in the future then that's probably the best you can do.

Because you can't change what you have already done

You may never know for sure if you did or not, and I think you’ll have to just accept that. In any case, however you classify it, I’m not sure it changes much anyway and I don’t think you should dwell on that.
Given that you are taking stock of your life now and clearly taking the right steps to be a good person, this circumstance in my mind is forgivable. Many people have done a lot worse.
As Western said, what’s important now is how you live the rest of your life. And, if it brings you peace, you could always reach out to your ex to ask how she felt and apologize.
