Waheguru ji blessed you with so much and still it is not enough? you say things like a love-sick school girl have you even an iota of the length of time you could be travelling before even getting to a human birth and then again you'd probaly be born a vaishva accordinrg to your mental state and Gurbanis faisla on you.
If you call yourself a good mother you will not destroy your childrens' lives for your stupid fantasy...pull your head out of cloud cuckoo land and re-engage with your own family and husband , tell this other guy to gets his kicks elsewhere
By your own standard, your taking the line from Dhan Dhan Sri Guru Gobind Singh Ji literally as well, the first ones to say Dhan Dhan Sri Guru Nanak Dev Ji wasn't God was the missionaries when they somewhat pretended to believe in Dasam Granth.
I bet your IQ is 1
You know Its wrong but you still want to do It. However think about how you will handle your children and husband after you have gotten what you want. It will be a little too late and you will realise that you slipped and will regret. Its up to you to choose to pass your test. Look at all the positive things In your present relationship and all negatives that could happen If you were In another one.
