To me it's about getting emotionally involved with someone and then finding there are many things that you don't agree on.
Romance is a risk (You lay your bets and then you pay the price). It can become an on again-off again relationship (You think you're gonna break up, then she says she wants to make up). The solution is to realise there are differences and accepting each other for who they are (A compromise would surely help the situation. Agree to disagree but disagree to part). It's about compromise for the sake of love.
