Parulji, one thing we must always remember. No one can bring good luck or bad luck to anyone. What is luck? Coincidence?
There is nothing such as a coincidence in life Parulji. Each one has to go thru wht he or she is destined to, has to learn what God wants them to learn and has to come out stronger with newer lessons... some losses, some gains. No one can be the cause of anothers pain.
One can be present during the phase when another is in trouble. You're only present in your husbands life Parulji when he is in trouble and needs support. What he is facing he was always destined to face. Your being there is also not a co-incidence or bad luck. God set this timing this way so that in times of his trouble, he has someone to be there for him rather than him fighting it out all alone. So that makes your presence in his life a blessing, a support... not bad luck.
You're the one helping him out and being there for him through the bad luck which was already destined to be there at this point of time. They say when we're in trouble, God sends angels.

You're that angel Parulji... never feel sad.
Om Sai Ram
