Partner who gave me ghsv1 is now ending the relationship.

So my partner who I’ve been with for almost 3 years now is deciding he rather focus on himself. I’m 21 f, and he’s 22. About 2 years ago, I dealt with hsv1 genital from a cold sore he had. That’s the only time I got it. He was super helpful and supportive and now I feel like all that is gone. I feel ashamed, don’t know how to deal with this on my own, I’m scared of telling a future partner etc. I know the reality of it and it’s not as bad as people stigmatize the word herpes because it was from oral and hsv1, but a part of me doesn’t know how to move on from this. Ive never disclosed to anyone. What do I do?
