To feel bitter?

[IceAndASlice123]

Helped friend through a horrible marriage break up. They met someone new 4 months on and just over a year later are blissfully happy. Seeing their partner just of a weekend and doing tons of fun activities where the sun is always shining and they couldn't be happier.
Yet with me, I had problems when I was supporting them but set them aside to help her. Barely hear from her now. I have a chronic bowel condition which means I cant get out as much, my job is under threat and I feel totally alone and used. Aibu to feel a bit fed up and used?

I guess I am then 😢

I think YABU to resent your friend overcoming her problems and being happy, yes.

Is it that you want more support from her now? Your post isn't clear.

Does she know the extent of your issues now?

Have you tried reaching out to her?

Does she know about your bad luck?

Yanbu if you have told her about your situation and she hasn't supported you.
Yabu if you haven't told her.
Have you?

Yes she knows I am struggling a lot. I feel she bailed on me when her life changed for the better

What have you got to lose by being honest with her and telling her how you feel? It seems like you aren't the friends you thought you were, so you may as well don't you think?

I'm sorry you're suffering.

What has she said when you tried to talk to her?

If I'm reading you correctly, it's not that you resent her happiness, it's that you feel hurt she can't be a supportive friend for you when you need her (even though you were there for her)?

Apologised but she didn't understand how I felt. Even though she went from texting me most if not every day needing support then stopped when she met her boyfriend. She said something along the lines of 'Sorry you feel that way. During that time I was struggling to understand his (Exs behaviour) and dealing with the fallout. I am now trying to rebuild my life. I have also put distance between my sister and myself.'
After that message we don't really speak now but I know she is 'blissful' with him and its not that I resent her happiness at all. I just think that its wrong how she ditched me as soon as she got 'better' as soon as he came along and that while I am hurting she is off being loved, having tons of fun and having a blissful time. Just hard to take and its not about resenting her for having a nice life, its how she's used me. I know I am better off without her but she doesn't feel the loss of my friendship at all. It's all sunshine, smiles, fun, and love in her world now.
