I seem to have trouble making and keeping female friendships. I have male friendships that go back decades, but female friendships either seem to fizzle out or I do something that upsets them and they distance themselves.
I am absolutely not saying I prefer men to women, or that I'm one of the lads, it just seems to happen that I can't keep female friends.
The most recent lost friend, is one who thinks I haven't shown enough interest in her life while she's had some tricky things going on. She's probably right, but I've had stuff too and don't expect anyone else to show more than a passing interest. I've asked her about it when I see her or if I had another reason to conract her, I've done favours relating to it when asked, but I haven't been checking in just because.
If I'm honest, in all my realtionships (even my DC), if I'm not with you and don't have a specific reason to, I'm probably not thinking about you. So, if e.g. I'm planning a night out and need to contact you about that, I ask about your life, amd am genuinely interested, but I won't contact you just to ask about your life iyswim.
Male friends seem to find that perfectly normal, and if we meet up having not been in touch for weeks it's like we've never been apart. It's only recently occurred to me that (some/most?) women aren't like that with their friends.
