please help with Advice!!!

Hi! I really need advice on this so if you have any good and helpful advice it would be a huge help!


I got engaged to my fiancé July of this year (2022) and he comes from a more wealthy background. When we told his parents, they started helping us plan. They have also said they are Willing to pay for all of it. I am the oldest of 9 (blended family) with divorced parents and one who doesn’t even talk to me. So my only financial support is my grandmother. But even then she can only do so much. I am also halfway through college while he just graduated. I never wanted a wedding because it’s a lot and my grandmas one wish is that I wait till after I graduate college. So with that this would give time for us to plan the micro wedding my fiancé wants. However, his mom his very used to being in control and it’s starting to turn into something we both don’t really want and not really having a voice in it. For instance, the location which we planned to be in Florida but it’s not the exact place we talked about anymore. Or even the date because they want it at this one beach and it makes it 10 days after my graduation instead of 17. So we discussed is eloping to somewhere but how do you would we tell them our change in plans without hurting their feelings. He is really close with his family which is why I was okay with a micro wedding but our plan was originally up to 50 people and it’s now almost 75-100. For any background on why I don’t want to take their financial help is that the one parent who doesn’t want anything to do with me used to use money as a way to manipulate me into feeling bad or anything else they wanted. So it’s a huge trigger for me mentally.
I know this is a long post but I just need some good solid advice. Thanks in advance!
