As a man I cannot comment from experience, but I would suggest that such a life-changing experience must be different for everyone.
Part of the difficulty in dealing with this circumstance is the 'perceived' approach, in other words, the way society as whole expects you to react and behave, and this psychological pressure can simply add to the difficulties involved in assimilating events into your life.
I think that anyone dealing with a circumstance in which society has behavioural codes - espcially in matters such as abortion, divorice, bereavement, and similar, should do their best to respond to their own feelings honestly, and make every effort to avoid feeling guilty or inadequate for not havng a series or reactions which have been dicated by time and social custom, and are the result of opinions of strangers.
Discuss the issues and feelings with those close to you whom you can be assured have no reason to enfore their own, or society's views onto you, but wil let you reach your own way of dealing with your life's changes.
