'Can't live with them; can't live without them'. Men say that about women, women say that about men, siblings and cousins say that about their families. The saying expresses frustration with someone or something you ultimately cannot give up.
I myself use this idiom to refer to people in general. As I advance in age, I become more aware of the wicked, treacherous nature of the human kind. Humans weaken you when you mostly need strength. They'll criticize you at a time when you're in need of support and compassion.
And yet, in spite of all, we need people, 'we can't live without them', their companionship , their wisdom or ..stupidity. (In a previous post I mentioned Barbara Streisand 's famous song "People, people who need people..."). We're constantly on the look out for interraction. Isolation is not the answer, and we've seen that during the two and a half year of pandemics.
In order to avoid getting hurt or wasting precious time exchanging futile words with some rude, infantile human being ,one can train oneself to keep distance from certain people. It's possible and quite efficient.
Anyway, I believe in God, pray to God for help and protection, and this gives me, among other things, confidence in my ability to handle humans.
