I feel so depressed

What's the secret of African church? I'v been in Africa since last year, And there is something goes very strange here ,I never noticed until recent date with a girl from UK. I met with her who was considered as half black in Immigration Department of Ghana ,and we had very pleasent conversation together,but when i tried to figure out what does she do for living in Africa ,she just replied me vaguely as said:"office work." However, she impressed me by her splendid smile and beatiful physical apperance , she was humble as sanit . i paid her my most respect . It's quite normal for a guy who wish to have a serious relationship. and i fully trusted her at the firt glance. AND Of course we had exchanged our numbers. When i tell her that i'd like to invite her for dinner on Sunday. But she told me she perfer coming to the church before the dining, then i came to church with her and the most unexpected thing was the whole church activties last MUCH longer than i thought , so basically, i spent my whole Sunday in the church and she has been persuading me to get baptized and commite my loyalty to God (, I don't even know what was that about neither the bible )and it was very werid about those priests'' behaviors (if you could search on youtube about African Church) you will understand more clearly about what just happened in front of my eyes .After eight hours in Church, i finally get my last patience killed ) i left without saying goodbye f2f instead of telling her by Whatsapp. and I also became more curious about why African churches are so crowded and fancy ? and why they are so eager to recruit new people for their church? i do think African church somehow does like cult

How do African Christian Churches work ?
