Jesus Christ very clearly mentioned that the only permanent separation that can happen between a husband and a wife is through death. This view, is based on the fact that God joined them, i.e., both are His children. Jesus Christ is also not against abandoning the spouse if he or she departs from faith in Him. The only exception for not marrying is unable to reproduce or raise godly children. While not directly, but we can infer that Jesus is not against remarriage after abandonment.
