My daughter is dating a jehovah witness
I feel that the previous answer might be a bit one sided.
0) First of all, persons who are not baptised as a JW, but only raised as a JW, are free to live their lives as they see fit (there is no infant baptism among JW's).
Baptised male JW's who do not follow this advise, might lose some 'privileges' (e.g.
they may not teach the audience in public anymore).
When they do marry, the same advice as given in 1 Cor. 3) Many persons who are baptised as a JW, fade away and become inactive (this means they do not go knocking on doors anymore for a period of 6 months or more).
According to some studies 2/3 of the children who are raised as a JW, do not consider themselves as a JW when they reach adulthood (this is apparently the lowest retention rate of all the religions).
There are different reasons why some sisters and brothers choose to marry unbelievers, either voluntarily or out because they have drifted away from close association with brothers and sisters.
So in these cases you have relationships between real JW's (who go door to door and to all the meetings) and only 'name' JW's (inactive ones who do basically nothing).2) Persons who are unmarried adults and baptised as a JW, are encouraged to marry only other baptised JW's (of a different gender).Again this is based on the advise of Paul to the Corinthians.It is however not a disfellowshipping offence to date or marry a non-JW.I do not know if there are any official sanctions against female JW's who marry non JW-men (the position against women is more relaxed, I think).
