What should I do? Wedding? As a result of studying in other places since childhood, some have been working in other places, so there are few friends in my hometown, and so are relatives.
This is easy to handle. Get both families out of here. Post you and her colleagues and friends.
Gather forty or fifty people, a table for six. Just find a small and medium-sized hotel and have a wedding reception.
Many medium-sized hotels have wedding banquets. Get to know it and make sure it's lively.
