So apparently we have to mention a situation like you're with your girlfriend or a boyfriend and your ex sent you a text message would you hide it from partner or what to tell them

See, I don't like that. I think that once you start deciding which ways to lie or manipulate your partner, that's when you need to be honest with yourself about the set-up of this relationship. Do you still want to be with them? Do you look for something else? Because hiding that that your ex texted you is not a good thing.

If I find a printer then I will tell them because I don't want her to overthink and feel like I'm gonna leave her for my ex I swear to trust me and know that I'm gonna stay with her and not talk to my exes and maybe go back to them only want to be with my partner

I would definitely hide it why she needs to know why

I think she has to know because if she finds out later she can imagine situations that aren't real answer yeah

No, I would tell them, definitely.
