I've been friends with a co-worker for almost 10 years.
To give some context as to her relationship experience: she's approaching the age of 50, has only dated one man briefly in college, and in all the time I've known her has never had a single date.
She swears up and down that she never wants to be married. Which I'd be 100% okay with (it's her life, not mine) if she didn't harbor so much anger towards couples. Outright she'll tell people that they're "crazy" for wanting to get married and that most married couples have just "settled" for their partners, and actually gets gleeful when she hears about a divorce.
The thought of partnering with someone sends her into a defensive tirade. She'll say she doesn't want a relationship because she needs her time alone, that if he wanted to spend time with her she'd tell him to piss off, and if her partner voiced his opinion she'd tell him to shut up. These tirades aren't triggered by anyone asking her if she'll ever get married. They often start by anyone referencing anything to do with marriage even if it has nothing to do with her.
I've been in a happy stable relationship for a while now but don't mention very many details about it because I like to keep my private life exactly that. Lately this anti-marriage friend has been very short with me and the slightest misstep in conversation will set her off (even if it's something as simple as her not hearing me the first time).
I'm just emotionally exhausted from spending time with her and her temperamental outbursts. It's hard to avoid her as we work together. But I'm just utterly sick of her attitude towards relationships and my "stupid decision" to get married.
