Help

Mmm tricky one.
I agree it would be awkward to invite some aunts and uncles and not others for an argument which has nothing to do with you.
I think it would be best to speak to your mother directly but nicely at an earlier point. Explain your position. Then if she does pull out of helping with funding you’ve got time to adjust your budget, etc. I think it would be quite extreme if she were to do that though. X

Her offer to contribute to YOUR wedding should not come with conditions, this is exactly why we have declined offers to contribute. I may sound harsh but your mum needs to be an adult and behave accordingly, you should be able to invite who you want to your wedding. You need to be honest and tell her that you will be inviting them as you have no issue with them and you hope she can be grown up about it for your special day and put her feelings aside. If she withdraws her contribution so be it, I can assure you if you give in on this there will be more demands (have been there) and your stress levels will be insane. It will de a different conversation but I believe once you stand up to her she will back down. Good luck

Don't accept any offers of help that come with strings attached. These are not gifts, they are ways of exerting control. You will be far happier having a smaller wedding without this drama than a larger wedding part-paid by someone who thinks their financial help gives them the right to dictate.
