There’s a TL:DR at the end, but I’d appreciate the help, forgive me if I’ve rambled on and on.

So, I got out of a long distance relationship about 3 ish months ago. The long distance portion was barely a month, and we broke up, and then, about a month and a half after the breakup, she said she’s moving on, and is going to see someone else. Now, she said this, and followed up with, don’t really call or text me, also meaning to say, I shouldn’t flirt or be suggestive with her, drunk text her etc. It kinda hurt, but I processed it, and 2 ish days later, sent her a long ass para, not salty or anything, just saying, hope she knew what she was doing, and that, I wish we had more time to talk it out etc etc, and forgot about it. Not a single iota of communication either way. In all this, before she left, she had written me a letter. It was so beautiful, talking about how we could really make it work, and give it a go, and she’d be in my arms at the end of it all. Now, the cliche romantic stuff aside, I genuinely do believe, that the way we ended, there’s just that feeling that if we ever meet again, we know we’d be with each other. It’s not like we hate each other after separating. But, my main question is, the letter, al the memories I have of her, does it make sense, to literally throw away all of that, and quite literally start over, from scratch? She might come back at the end of this year, and idk what the future holds. I do hope this subReddit helps, because the standard advice is “get over her it’s never gonna happen” but this doesn’t feel that simple. I can see a different girl tomorrow, and not give it a minute’s thought, and I won’t be thinking about my ex. But as it stands, 5% of me, is always like, hold on to her. If you throw away/delete everything related to her, that’s basically telling yourself that she doesn’t exist in your life. Because I’m not sure I can start over from scratch with her, ever. Whereas if I keep that 5% at the back of mind, it feels like it’d be easier, getting back together with her.

TL:DR- Should I completely erase my ex from my life, or maybe still keep hope in the back of mind that everything might work out someday? Cause cutting her off completely might prevent me from ever being able to love her again, ever, whereas not forgetting about her would make it easier to potentially love her agian.
