You must have had a reason why you left your husband. If those problems are not solved, you will face the same problems when you go back. The other thing is: how will your husband treat you when you come back? I would recommend you a marriage counseling before you move back to your husband.
Marriage. Can always get another job
Give it back to her. Or give it to another female. Do not wear it!
A widow should not perform the kanyadanam ceremony in Hinduism. She should not give away her daughter for marriage. It is the girl's uncle or male guardian who should give away for marriage since her father is dead.
If it was passed down from your family I think she should give it back. However, if you bought it for her its hers to keep.
No, you do not have to give wedding gifts back to guests when divorcing within the first year of marriage. The gifts would be part of the contents divided by the husband and wife.
No the guy should. The girl should give him signs
Maybe you should give her another chance especially if you have children together. If she is truly sorry you should give it another try. If you can do it, you are truly one of the cooler ones, and have a lot of courage. Be careful with it this time though.
Give back to the owner
Only you and your ex can answer that. A lot depends on whether your ex wants to get back together.
you should give her some flowers or chocolate girls chocolate
you should be at least 21 before you get married
Yes, if there is a wedding in a church and a reception then you should give a gift even if it is a third marriage.
