Both in our 20s, I've got a baby and she doesn't. Known each other for 18 years now. We speak every day, when we're together we get on incredibly well, she's been there for me in lots of tough times (and I've been there for her!), she loves my child and never misses a birthday or important date, so I can't really fault her as a friend in any other way.
Since the last couple of years whenever she makes plans with me it's always very vague. Like "let's meet next weekend but let's keep it flexible: Sat or Sun depending on when my mum decides to come to town" or "I'll come over Friday night maybe, if my period cramps aren't too bad" or "I'll come some time in the afternoon, depending on when I finish brunch with X friend" or "let's see how I get on with job applications and if it's all good we'll do something Saturday". She seems to specifically pick days to plan things with me when things are vague or uncertain? Or maybe it just feels this way? I think maybe she does it because we're close so maybe she feels she can keep things flexible with me or because im often just home with the baby anyway (but still want to know what I'm doing and when!!). She doesn't seem to do this with other friends. And whilst each individual time it's a reasonable excuse to keep things vague, when you take it in combination with all the previous times she's done it I feel unimportant.
AIBU to want her to put more effort into the friendship or to feel unimportant as a result of plans always being "vague"?
