Charli has spent her life giving to others both in her personal and professional life, in the same vein she now believes she must always give and help her partners, even if they aren't asking for it. This tends to be a common trait of co-dependency - one-sided relationships where the needs of others are put above your own to feel validated and 'needed'. In Charli's case her selfless need to help, fix and please others before herself is what is pushing her partners away.
