I am filled with so much guilt of not being able to save my husband and not being present around him from past 25days before he died
I don't think that this was your fault. I'm not sure there was anything that you could have done that would have prevented this.
I think the love that you gave him probably made him much happier than he otherwise would have been. There's no reason for you to feel guilty, since you gave him so much love.
But what others told me put me more into grief that he would have taken birth somewhere else.You won't get him as your lover ever again.he had a part to play here ,when it got completed his soul left his body
I think that the people that you are talking to may have good intentions, but do they really have direct knowledge of such things, or are they simply parroting a religious ideology?
I don't think that you are under any obligation to believe what these people have told you.
i just want an assurance that one day he will meet me again
Many people here say that they have dreams of seeing their loved ones again. You may want to try meditating on seeing him in your dreams each night before you go to bed. I think if you do this, it's very likely that you will see him again in a dream.
Also, your child is a flesh-and-blood embodiment of him, you, and your love for each other. Loving your child is in a way also loving him. You will probably see aspects that remind you of him in your child as your child grows.
As painful as it is to have lost him, you probably don't wish that you had never met him. In time, the pain and grief of his loss can be replaced with a joy and gratitude that you found him.
