I couldnt find an answer to this. But assuming you go NC for a few weeks or months, then eventually start talking again and dating. How do you deal with the fact that your ex may have dated and slept with one, or several other guys in that time? After all, if you are giving her no contact, she might feel vulnerable or unwanted and go on the rebound...
This is just my worry about my ex, though i do plan to casually date others during this time, i know that if we do ever hook up again, i will struggle not to ask about her history since we split, and if she says shes slept with other guys in that time, i know it will hurt, even if i may have slept with others as well.

Why do i think like this and how would i control it? I cant be the only one to wonder this though?

If you are the one initiating the NC format, clearly you are granting her permission to do as she pleases, as well as yourself. If SHE initiated, she is clearly giving HERSELF permission to do so, and she likely will.

If you are on a "break" all bets are off.

If you recontact, you must be able to accept that possibility, and deal with it. Or you have to move on.

Anything more than a few days is not to re-evaluate the relationship, it's a breakup.

Agreed. If you can't accept that every woman you ever have sex with has had another guy's jizz on her face, you'll never get laid or have healthy relationships. Look for positives in the situation;:

1) You are now free to fuck whoever you please and I strongly recommend you start this immediately and aggressively. The more women you sleep with the more she'll want your dick, no matter what she says. Don't brag about other girls though. The more girls you fuck the less you'll need this girl.

2) You no longer have to answer to anyone. If you feel like going to play poker at the casino until 6am, you are free to do so.

3) Also use this time to catch up with the guys, your bros you've been ignoring all this time need some love too <3

4) If she's out fucking other guys and you're fucking girls thats a fair deal. If you ever sleep with her again, you will be better at fucking and she will be better at sucking your dick. You'll rarely hear any guy put a positive spin on an ex girlfriend sucking other guys' dicks, but I went there, I said it and it's true!
