Nonsense!
That is your weak excuse to use a religion for why you can not do something!
Nowhere in the Bible does it say you can not participate in Online Forums and your Priest would even tell you that you are going to far.
Prayer, Reflection and listening to your inner self will tell you the truth.
The Devil as you call it can not tempt a pious man and if you are weak then that is on you!
You must accept responsibility for your failures, sins and realize when you do then you will then find the truth you are looking for.
You blame others for your relationship but did you reflect on your conduct during the marriage?
Maybe you did nothing wrong but maybe you did and never saw the signs of what you were doing to cause the destruction of your marriage and home...
You should join a group within your Church Community and talk things out and see different points of views and reflect on it.
Jesus was a man that taught us forgiveness in his teaching while trying to understand we are mortal, we sin and we must repent and learn from our failures in our father eyes...
So just chill on blaming others for your straying from the path and guess what you will stray daily but take a moment, sip some tea and sit and reflect on your daily sins and ask for forgiveness and try not to repeat them...
