Tony realises she wants to be killed and in her deranged mind being killed by her lover would be a fitting death. A grimy death at the hands of a strange doesn't have the same appeal to her sensibilities.
Ultimately, Tony doesn't give a fuck if she kills herself or not, she just wants her to leave him and his family alone which he achieves. Him being upset when he learns of her death is just the fleeting sense of guilt he gets every now and again.
