My father became religious and it ruined my family

My father about 12 years ago. Started going to Yoga classes. A year later he started becoming religious in the ways of Buddhism. He went from growing up and living his entire life as an atheist to Buddhism in a year. But over a decade it got worse. He became more and more involved in the religion. Listening to religious music, meditation instead of spending time with his family. Then listening to yoga teachings and spending way too much money on retreats and so on.

Ans then he started using meditation and whatever God he believes in to excuse things he wants to do and irrational choices. Taking credit loans, divorcing my mother and getting remaried in 6 months after that.

It broke my family apart. I wasn't living with my family since I moved our before it became bad but my sister was. Now my mom can barely live and support my still teen sister.

He has been using visions or something of that sort coming to him during meditation to excuse all sorts of other things too.

And to think it all started with him not eating meat anymore. Then no more milk products.

He said he would never force it on us and it took him a whole 4 years to start trying to force it on us.
