Possibly, although he was quite a bit older, so who knows how old he would’ve lived until. Their marriage was probably somewhat similar to the two she had with Richard Burton. She was so distraught over Todd’s death that she obliterated the marriage of their friends Debbie Reynolds and Eddie Fisher. Todd was a very different personality from Fisher, a very aggressive type, a go-getter, a showman. He liked to get rough with Liz, and she apparently enjoyed it. When she discovered Fisher was essentially the antithesis, she didn’t like that, and tried to get him to act more like Mike. It didn’t work, and she went on to Burton, who was more to her liking.
I've always wondered if the reason Virginia Wolf worked so well was due to the nature of their own relationship.
