It is reported that Abbott was married before she was together with De Niro. However, there is no information about it.
The only known husband of Abbott is De Niro. The pair met on the set of Martin Scorsese's Taxi Driver, where De Niro played the role of Travis Bickle and Abbott portrayed a concession girl.
The two got married after a couple of months of meeting each other. They tied the knot at the beginning of 1976.

Their relationship was pretty low-key, but the couple often attended events together. For example, Abbott went as her husband's date to red carpet events, where they were photographed together.
The pair's marriage lasted for only 12 years. Then, the two parted ways and got a divorce in 1988.
After her split with her husband, Abbott has remained out of the spotlight. She worked on only three movies after the divorce, Jo Jo Dancer, Your Life Is Calling (1986), Before Night Falls (2000), and Soliloquy (2002).
It has been two decades, but the actress has made no appearance. It is unknown what she is doing now and if she will ever act again.
The only glimpse people get of her is via her daughter's social media. On the other hand, De Niro has been linked with many women after Abbott.
Soon after his divorce from Abbott, he started dating Toukie Smith from 1988 to 1996. The couple was blessed with two children, twins Julian and Aaron.
A year later, De Niro became a husband to Grace Hightower. But once again, their relationship did not last long.
Their son Elliot was born in 1998, and the pair parted ways in 1999. But the divorce was not finalized, and the two renewed their vows in 2004.
In 2011, they welcomed their daughter via surrogate, and in 2018, they split for the second time. But this time, divorce was finalized.
