Holidays on your own

Dilemma. Started holidaying for the first time alone 10 years ago. We are lucky to holiday in the sun numerous times throughout the year. Four years ago both of us had wake up calls in the health department. I am fully recovered but OH left with lifestyle change issue. No problem but he announced yesterday that he is not going to mind me holidaying in the sun more often without him. What do I do . I love the sun and the time on my own to keep my head above water in the UK. If something happened to him and I was not in the country could I deal with the fall out. Help please
