We have been friends for about 15 years, been through a lot together, supported each other, never had an argument.
We had our DC within less than a year of each other 5 years ago and from then on I noticed that she seemed distant sometimes and just not seeming as friendly even when we did meet up. Our DC barely know each other despite an 8 month age gap as she is not 'available' to meet up all together, only about 1-2 times a year. She went back to work after mat leave and I am a SAHM but now looking for work (DH thinks me being SAHM could be an envy issue).
The past two years she has not bought me a birthday card, when previously we have always exchanged cards and gifts (birthdays are two weeks apart this month). I still gave her a card and gift for each birthday (hers is after mine), and I got a text late in the day saying 'Happy Birthday' and nothing else, i.e I hope you are going out for a nice meal etc with DH and DC. This is all out of character with the way we always made a fuss of each other's birthday.
We last saw each other just prior to lockdown along with a mutual friend. In the past 6-12 months she rarely texts to just say hi or share some news; if I text I'll just get a reply of less than 5 words. Never asks how I am, any news from me etc. Since Christmas I'd say I rarely hear from her unless I initiate contact. I only text once 2-3 weeks or more since she's become distant, so I don't think that classes as being needy.
She always claims to have no money for meeting up for dinner, but about each month there is photos on Facebook with groups of other women at restaurants and bars. She does have long-term issues with her DH (not abusive, other issues which I won't mention) but this has been so as long as I've known her and she's been quite open about it. She last confided in me about 6 months ago with her DH's latest issue and I listened as I always do, did not offer advice or judgement (the issue is not something I know anything about anyway), and reiterated several times that I'm always available day or night for a listening ear.
Another curt 3-word reply to a text today and I'm thinking I should probably just stop contacting her and see where the friendship goes. DH says it sounds like for her she's moved on from our friendship for whatever reason and should back off.
I feel so sad and upset as I thought we were good friends and she once called me the sister she never had
