I didnt grow up with my cousins. But I do know their parents and the kind upbringing they had
As for if it doesn't work out... thats why Allah made divorce halal

but Alxamdulilah I married a submissive and obedient wife who apologises even if she's in the wrong
And what motivated you to make such a decision? Many people come from good looking families but are not attracted to their relatives. Aren't you afraid of genetic anomalies or causing family rifts if you marry your relative and it doesn't work out.
I have seen problematic outcomes from relative marriages such as kids with a greater likelihood for disability to family feuds and higher rate of physical health problems and mental illness. You essentially reduce reproductive fitness and increase odds of a number of health conditions: cystic fibrosis, thalassemia, down’s syndrome, heart diseases, autism, blindness, deafness, neurodegenerative diseases and rare genetic disorders.
Good thing the generations before me aint related and my wife is half somali

my main concern was ruining family relations but those doubts lessen everyday

I found the perfect girl and I'm a decent guy, notin can go wrong.
Do you realize Arab societies especially in the Gulf would marry their cousins because they were isolated and would marry who they meet? I doubt access to unrelated individuals was your problem. Also some communities practiced paternal line cross cousin marriage in order to preserve wealth within a family. Their primary reason was being motivated by access and/or finances.
I felt isolated with all the women using me for my money. The last girl I dated tried to extort me to pay for her brothers wedding

under the disguise of buying a 5k dress. Istikhara and with the help of Allah all her plans were revealed. And when I cut things off I found out she was a divorcee,

its calm, but why would a divorcee ask for 20k mehr. She shouldve also told me this when I asked her if she had xarir. Its a crazy dunya and I decided to settle for my cousin
