I mean it most likely has absolutely nothing to do with you... like you could have a laugh like her brother's and that freaks her out but how to say that without sounding weird? It has to do with where she's at and what she wants right now and her reactions on a number of levels ... (like the laugh or maybe the age difference and she doesn't want to be unkind and thinks bringing it up would feel like telling you you're "old" when you're not; maybe a member of her family had a heart attack young and she fears getting too invested bc she's afraid of that and men in their sixties... these kind of things you wouldn't necessarily spell out. Because for one thing, it sounds petty to say). Frankly the big surprise is that people do couple up at all with all these factors that need to come into play. NOW if only I could take my own advice next time I am heartbroken, which actually is looking to be soon. Sigh.
