Feel abandoned by my best friend

[Benji13]

I have been close friends with a gf for the past 20 years. I've supported her through many dark times over the years (she suffers with depression) and always been there with a listening ear.
I'm not in a brilliant place atm for various reasons and just feel abandoned. She spends a lot of time with a new friend of hers and while she does still see me occasionally and is sympathetic the attitude is 'chin up'. I feel so let down and wonder if I should tell her.
My dh says it's simply that I've ceased being useful and I should move on.
I'm hurt and disappointed 😔

I’m not sure that addressing it with her would help. If she regularly suffers with depression, she may not be able to reach out emotionally (I say this as someone who has had to train myself to show empathy). I’d be inclined to withdraw and concentrate on those who support you. Hope that things get better for you very soon .
