My Life Changed

I'm the only boy in my family, my 2 sisters are married and older than me. My parents run their own business and I'm going to university. I met my now wife at university which caused our marriage earlier than we would've planned as she got pregnant. But I'd done one thing in my life, at a family get together. I met and got on very well with my great uncle, the so-called black sheep of the family. He had done something to really piss off the rest of the family. But nobody was willing to tell me what he had done, I know my sisters didn't know either. But they toed the family line and avoided him, he was only there because of my grandmother wanted him there, as her brother and only male sibling. He was older than her and had left to do his own thing before she was 10. But he promised to write to her and always did and she hasn't told me what he had done either. But at her birthday party he wasn't talked to other the arrival and departure talk. Except by me I saw him sitting alone and talked with him and got a few glares from others. I also kept in touch and relayed his letters to my grandmother, otherwise she wouldn't have gotten them. Fast forward 2 years and I was in the stew as they say I hadn't gotten my now wife pregnant. Just before the birth of our son my uncle passed away and I was the only one mentioned in his will with the condition to look after his beloved sister my grandmother. Turns out my black sheep great uncle was very rich. Also, after everything was settled and my inheritance was being referred to as Satan's wages and other such things. I was set for life and made sure my grandmother was looked after. Still with a year to go a university I finally found out what my great uncle had done. It was the evilest thing anybody in our family could ever do. He rejected the church we were a part of and didn't believe in there being an all-powerful being to boot. Left to make his own way and done very well. With family trying everything to stop me helping my grandmother, I got her to agree to live with me and my wife and new baby boy. At first as a visit to see her great grandson, then having her make me her legal guardian. Much to the annoyance of my family, my gran enjoys not going to church every Sunday and hearing the gloom and doom sermons. I expect to be ex-communicated as a result, but their tries to get me removed as guardian failing as I live close to the medical facilities my gran needs and able to provide fulltime care for her. Makes it hard for the rest of the family to overcome, their only complaint being her not going to church as often as they would like. I just said it depends on how she is feeling on the day or the weather and that crushes their arguments. I have one problem those, I have to go to church with her when she goes. My wife is again pregnant and I thinking of using it as a way to avoid church more often.
