I (23F) haven’t been in a long term relationship before so I’m not really sure what the norm is, but my boyfriend (27M) of about 8 months broke up with his ex of 2 years about a year before we got together (which I know from being friends with him at work, I never knew her). I’ve never asked about her but they still follow each other on social media and have posts up together, is it weird for me to ask about her? He still likes her pictures and has them in his phone which i’ve seen in passing but I’ve never brought it up. I don’t think I’m jealous I just want to ask about it but don’t want to seem crazy? Idk if that makes sense but any advice would be appreciated !!
For context we met through work and are different nationalities so not much friend group overlap, so i know basically nothing about his past relationships
TL;DR- How do I ask my bf about his ex gf without seeming insecure?
