Should I tell my girlfriend (28F) that my ex girlfriend (25F) and I matched on Bumble? I’m (30M) torn because I’m not sure how my girlfriend will react.

So I downloaded Bumble to find women in my area to match and ask out. I swiped on a few women and closed the app to go to the gym and work out. Come to find out while I’m working out my ex girlfriend from a few years ago is in the gym. We say our hellos and go back to working out. I come home and go to open Bumble to see my matches and lo and behold my ex is one of them. <br><br><br>Now, while I am currently in a relationship, we’ve matched before when we were dating and she unmatched me when we broke up. So I believe she matched me not realizing it was me, but I’m not sure. <br>We didn’t talk much at the gym but she mentioned she got a new job and is pretty busy with work. I’m not sure if she’ll message me, or just unmatched me after realizing it was me. <br><br><br>Now, I bring this up to you lovely people because I’m not sure what to do. On one hand, I feel as if I tell her it’ll just irritate her, and make it seem like I’m doing something I shouldn’t be, because what man gets matched by his ex and doesn’t tell his gf? <br><br><br>On the other hand, not telling her seems like I’m hiding something. <br><br><br>My gut tells me to not tell her because it’ll just cause a fight and will probably lead to a “you’re doing something behind my back” conversation which I’m not in the mood for, but tell her and keep transparency in the relationship. <br><br><br>What would you do in this situation?
