I would move on with your life get remarried if that’s what you want and live your life to it’s fullest. You only live once, don’t waste it.
As far as religious beliefs are concerned the Bible has been changed over the centuries to fit the ideas of the church leaders. Many of the things in the Bible today were not there 500 years ago. If you want to check one as an example go to Revelations 5:9-10 in your Greek interlinear. In the original Greek you’ll find that they are not mentioned as kings and do not reign over the earth but on it as priest.
Then ask yourself if Jesus would really want you to destroy your life and future because of a liar? Is that loving ?
