She demands an expensive wedding

I’m 32 and my fiancé is 27. Our wedding date is set for August this year. I thought I would be happy about this, but it is only stressing me because she and her friends are making the wedding too expensive. Our initial budget was Sh300,000, but this has shot up to Sh610,000 currently.

Her justification is that friends and family should contribute to our wedding just like we do in theirs. Initially we wanted a small wedding because we are not financially stable. We had planned to contribute a third of the initial budget, but now it seems our contribution may go up to Sh350,000, which is way above my means.
