I am glad they are there for you, my friend. Family is important.
I'm close with my wife family since in highschool!
Although my wife was my classmate, actually I'm a year older. It's because I was naughty and must spent two year in grade 8 in seconday school. In the first year in grade 8, one student in another class was her brother.
I meet my wife in grade 12. Then she told about me to her family. So, when I visited her home she told her mother "Mom, this is the boy I've told you". Her brother asked me "Remember me?" and he told his sister "yes, this is the boy that I mean". Immediately I became close with her family. Even sometime I ate in their house.
There are 8 children in her family. She is the 6th. Honestly, I was shocked when I visted her home. She lived in very small house with only two bedrooms for 10 people.
I started to buy some goods for her, and even I used my saving to pay her study cost in a computer course after she told me that she was sad. She wanted to have higher education but her parent could not afford to pay the cost. It surprised her family. They did not think that I was very care to her.
But when she started her course I started to far from her and her family. I was busy with myself. Later when she finished her course and immediately got a job, I had been gone from their life. It's because I meet another girl, and I wanted to marry this girl.
It made her felt disappointed when she knew it. Then she tried to contact my mother, and knew that my mother did not approve the girl who I chose. In another side, my mother saw her as a girl that better than the girl who I chose. Immediately they became close and she started to close with my family.
So, when the girl who I wanted to marry decided to not marry me, I decided to back to my ex-classmate again. I back to her family again, although I got some satire from them such as "I hope no one will angry if you gather with us" or "Don't you go 'there' again?"
My wife family often held activities together, sometime the big family went to other places in group. With me too, of course. And even I more often gathered with my wife family than my big family. It made me always close with them.
And there is another reason why I still a member of my wife family. My kids. Yes, my kids have blood connection with them.
