I appreciated PhantOS's posts in this thread. You only ever heard one perspective on this stuff. I've been working through some problems of my own recently and it's refreshing to hear somebody say that love and relationships can be unhealthy for you at times and that it's
okay to be single and focused on yourself in the early stages of adulthood. I only ever hear people talk about how great and awesome and epic long term relationships are, it's rare somebody talks about how detrimental they can be. I'd be willing to bet there were at-least a couple people who read through this thread and felt the same way.
You can also choose to be alone but given my past experiences with it, it's not ideal.
It's not really about being alone, but building meaningful non-romantic relationships with the people in your life. Isolation is dangerous and I'd never recommend it to anybody. Realistically, a network of dependable people is more constructive than a long-term romantic relationship.
