Of course not!! Your beliefs are your beliefs and they should not stop you from interacting with your friends and family.
What a lot of new Muslims find, however, is that the lifestyle of a Muslim is not conducive to that of a Western individual.
As Muslims we dress more conservatively/modestly, we do not drink Alcohol and our overall behaviour is very different to that of someone who is not a practicing Muslim.
It is hard for the family and friends of the ‘new’ Muslim/Revert Muslim. They are confused and bewildered by your move to Islam. They most likely have little information about Islam and Muslims and they have misconceptions which have them feeling afraid.
It’s important to keep contact with your friends and family. It’s important to let them know that you are still you and that being a Muslim is only going to improve who you are.
On average some reverted Muslims say it can take any where from 1 to 6 years for family/friends to accept or understand your being Muslim.
The Revert Muslims Association offers support to all those who become Muslim by means of the forums/msn and phone.
