No, dolphins do not keep their mate for life.
Males and females do not stay together but a calf will stay with its mother.
Bottle-Nosed Dolphins are ready to mate when they are about 15 years old. That does seem a little odd to a human but that is the time of life when the dolphin is ready to mate.

Some species are monogamous, others polygamous. The answer is actually one dolphin or monogamous, meaning they have one mate for the rest of their natural lives. They are actually more intelligent that we are, but very much like us in the sense that they are the only other species in the world that enjoy sex for activity and that they are one of the few species that inhibit signs of jealousy and treachery... not to say that dolphins are bad people. Polygamy is like mating without a solid partnership or taking many spouses. Apes would be polygamous, meaning that they would mate with every female in the tribe, though take no partner. In some middle eastern countries, men would take more than one wife.
No. Dolphins can kill sharks by blocking their gills.
