Seeing some stories in here about how badly it goes to follow your exes so I’d like to offer an alternative story. I have no idea what’s going on in my ex’s life and it’s wonderful. She could be doing amazing, could be terrible, no answer would make me happy, and I’m happiest with no answer. I’m happily married now and don’t care.
Yep I second this. I have gone NC with all my exes. Two wanted continued contact but that's just not me and sometimes people ask me what they're up to and I can happily respond I have NFI.
In one case I found out they lied to me about why we broke up and the second she became a horrible, vindictive person after we broke up and started spreading lies and rumours about 6 month after we split. Originally both breakups were quite amicable and soured and they didn't understand that that had quite a lot to do with my decision to 100% no contact.
I don't think I'm 100% against it now that I think about it further. I just seem to have a history of dating people with an underlying hurtful streak and/or poor empathy...
