@Caliber as a matter a fact my son dated a ´worldly´ girl for about 10 months during 2012/2013. She visited us a frequently and we did invite her for dinner with us. They broke up last July. During the time he dated her (which was no secret to anyone) there was no change in the way brothers and sisters in the congregation behaved towards him.
At the same time i have spoken a few times with him and told him about my own experiences with ´worldy´ girls and that its easier when you befriend someone who believes the same things and upholds the same values.
My son starts his higher education after next summer, and ofcourse i pay his education. His aim is to become a highschool teacher in a few years from now.
