I think audiences can deal with these mature themes.
If somebody ever says something is a mature theme, it's bound to not be. I mean, you shouldn't fall for that. You can make it sound mature, but anything that's about being mature is pretty immature.
Immature love says: 'I love you because I need you.' Mature love says 'I need you because I love you.'
Themes recur again and again in my work.
