I feel horrible even writing this because I adore my younger sister and I don't blame her for any of this whatsoever. But.
I have been married for several years now. I am a woman and I am married to a woman. As such, I didn't ask my parents for help with the wedding because I know my mother doesn't approve of or believe in gay marriages. The whole wedding only cost £400 because a) I knew my mother didn't want any of my family to know about it because of how it might "reflect on" her, and also b) I don't believe in spending a lot on a wedding anyway. So we paid for that ourselves and it wasn't a crippling financial burden. My parents did not come.
Now, several years down the line, my sister is going to get married. A bit of background on my parents: my mother in particular has always had a huge emphasis on everything being "equal." If one of us wanted a monetary gift for Christmas instead of a "thing," the other would have to have the exact amount of money, etc. So, while I always thought my parents might spend some money on my sister's wedding, I had expected they might offer a similar sum of money to me to use for a house deposit. I have hinted a few times that I'd really love to get on the housing ladder and had little response, so I thought, ok, they don't want to give us any money. Fine, they're not obliged to. I know they're relatively well-off but it's their money.
Now, however, it turns out they're giving my sister £30k for her wedding. To say I'm fuming is putting it lightly. First of all, I think that's a ridiculous amount to spend on a wedding, but moreover if they have that much to spend, surely it should have been split evenly between us? The fact that I didn't have an expensive wedding and ask them to pay for it (they wouldn't have anyway) surely shouldn't mean they give my sister the whole lot of whatever they had in mind as "spare"?
It doesn't matter in the grand scheme of things, but it certainly doesn't help with the underlying resentment I feel towards my mother for pretending I'm not married to my partner.
