long distance advice

I’m in a long distance relationship and I kinda did something so bad the other night. I was beyond black out and my bf knew this and we ft that night too I just don’t remember any of it. Later in the night we got off the phone and my ex texted me out of no where. I decided to go to his house just to speak to him. Nothing sexual happened not even a kiss. But I feel insanely guilty about it because I know it was wrong even going there. I don’t know what to do because I don’t think I can tell my bf because it might break up with me or be so upset but at the same time the guilt is eating away at me… any advice
