Simple personal opinion regarding relationships

Recently I have seen a lot of negative posts from guys regarding relationships, some even can go into generalising girls/women and assume that every girl is like this, lidat. To be honest, in the past, I have been through this before. Encountering lots of fake profiles online, girls with ulterior motive and dating apps not even a single like after so many years of attempts. However, now I have switched my mindset, ' work on myself, take care of myself and focus on your goal'. Guys and girls, what are your thoughts?
