My friendship with bff is Falling apart and I don’t know how to fix it

Hey
So I 32F have a bff from 6 years, we have been through alot together. We practically watched each other grow. So she moved to Europe about 2 years ago with her husband and I am still in 3rd world south Asian country.

We used to talk on phone alot all the time 2-3 hours a day then as she got busy and a job and language classes it shrunk to 2-3 times a week which I’m fine with. I don’t have much of a routine so I let her do the call initiating because she has a husband and a proper work timing. I freelance and am single so pretty free. I always pick up

Lately, she has become distant and this is my first time dealing with something like this and I don’t know what to do.

I had a boy problem, she warned me against it but I still went ahead and fortunately it ended in a month. I realized that she was getting annoyed listening to my story about the guy , I’m very sensitive to changes in tone and other demeanor. Once I got hurt I took her and her husband’s advice. Her husband bashed me when I got hurt by the guy , now both of them I don’t question their intentions when it comes to me. Her husband said things like ” your market value is downing”, ” wtf is being attractive to your spouse ” ” you are being too picky etc ” the next day she calls me and says that you are being unrealistic because I demand ” Respect,kindness,empathy, emotion intelligence and other intangible things”. I never even ask how much someone makes or if they are handsome for me it’s other things but she thinks this is unrealistic and I should just pick someone who will provide and respect me and just marry him.

Small details: Her marriage is pretty shit, her husband doesn’t treat her with kindness and respect. They are good roommates who travel. She wants to leave him but don’t have the courage yet, these are her words

I don’t know what to do ? I did ask her that she feels very distant she said no I have just been busy and I am always the one initiating calls etc etc.

I have been there for this girl for 6 years through her husband problems , taking care of her family when needed but she just got fed up of mine and I decided to not share boy problems with her but now I can’t really find things to speak about. It feels forced.She went on a trip with her husband and didn’t even tell me, she will be back in 5 days

My suspensions
1. She once said she was jealous of my single life so maybe it’s those feelings coming back

1. Her other close friend recently got married and her man is over all good but compares his wife to celebrities so all of them are. Compromising and maybe they relate to each other more. I’m just the well to do single friend amongst married ladies

What do I do ? How do I fix this?

TLDR: Bff acted annoyed with my boy problems after years of me supporting her through a bad marriage. My suspicion says she is either jealous of my single life or related more to her married friends now. She thinks I’m unrealistic for wanting a loving partner
