..... IMHO.....
1. You were a victim of gossip
2. Your area has a gossip problem of this sorts
3. Elder was mis-stepping his position and sharing his personal opinion without regarding it might be taken as a directive.
4. The WTS has long encouraged couples to not have children in this system of things (oddly enough I think that first suggestion was found in a book entitled "Children")
5. Bit concerned that this Elder would be so 'familiar' with you regarding those sorts of relations, you not being married yet and all at the time. Is your husband also in the truth?.....just seems the sort of conversation a man would have with another man since many witness women don't go onto the pill until after they are married because many see it as 'stumbling', so the withdrawl method or condom is often employed those first few days before the pill kicks in......
5...... honestly it is good advice, I mean I know some still have romantic notions about that but relationships are already new at the beginning of a marriage and waiting until the marriage is firmly established before starting a family is alway good footing.
