Definitely don’t bring it up imo. Because if that was me, my brain instantly goes, omfg she notices it it’s so bad, how many times has she noticed does she thinks I’m stupid etc just spirals really but that’s me. It’s a tricky one because I think everyone’s different with it. Me personally if it’s someone lm dating I’m upfront about it, that’s just me I’m trying to be more upfront about mine. He might open up, if he does just listen, tell him it doesn’t matter and he’s so much more than that. But my opinion don’t mention it, just be as supportive as you can. Act normal, because there’s nothing worse for me when people treat me differently because of it.
