Terry's marriage is not so smooth either. Livia decided she definitely wasn't having any more kids and, unbeknownst to Terry, she arranged her own contraception.
Livia liked sex, lots of it, but not the result of that sex, except for Luka who, despite being very difficult, remained the apple of her eye. Consistent with his Catholic upbringing, Terry wanted to have more children. Livia's failure to get pregnant again, when it would be appropriate and he had the money to support her and the children, made things a bit tense between them.
To add insult to injury, Livia blamed Terry.
