Setting realistic expectations

I am working towards setting my impossible goal which is to find myself in a loving relationship which makes me happy. I have realised that one of my obstacles is that I have expectations on how people should show me love, and when they don’t do it in that particular way I feel unloved and it makes me very miserable and causes me to think that I am not worthy of love. Can you recommend the work in Scholars that would help me with that please.
