Nt sure I know exactly what you mean, I tend to relate 'high matenence with cost, as I sit here in my holey ripped outfit (comfy) and tping with beat up nails (bleach is bad for nails) and my hair up in a simple bun, oh with a baby on the knee
...I have a feeling I am not 'high matenence'!
But if you are looking at emotional needs, well that might be free but I am sure it is tiring for DH to have to constantly reassure me (do I look fat in this? Do I still look pregnant? etc, etc)
