Well.. Just to share, I experience this religion problem that cause breakup.
To make it simple, I'm Catholic, she's Buddhist.
My family is those that rarely go church as if Christian just the name of our religion
Her family is very religious Buddhist that follow all sort tradition and belief.
Everything went well, till the days her parents found out I'm Christian.
Objection, arguement, conflicts... Turn our relation badly.
My gf choose to leave me, I let go willingly.
