Is it possible to have part of my memory wiped?

The past couple months or so I was in a relationship, and it turned out crap like I figured it might, but you can go back and read through it yourself.

The problem is that when I remember it, there are parts that were really good, and I feel good remebering them, then I snap back to reality and think “what’s the point”? I’d be better off just knowing that I tried it and it didn’t work than remembering those parts of it, is there any way I can get rid of these memories specifically.

I know its unlikely but it really would be great. I don’t need these memories, they don’t do me any good.
