I am a 30yo, single and childfree woman, have been in two long-term relationships by now, and don't really plan on getting into another, or at least don't plan to go specifically looking for one. I'm fine with more casual romantic relationships, but don't like all this 'other half' nonsense, or the assumption that a single person is incomplete and should be in a constant state of searching or waiting for a partner to come along and fix them.
I ended my last relationship because my lovely partner wanted to have kids and get married, and that sounded like a prison sentence to me.
I have never been comfortable with the amount of "merging" that you're expected to do in romantic relationships, and how that relationship is assumed and expected to trump absolutely everything else in your life - and that if it doesn't, then there must be something wrong with it. I recently came across a term for this, the 'relationship escalator' and it explained so many of the feelings i've had over the years about this narrative that so many people are so committed to about there being only one right way to 'do' romantic relationships, and that we all must 'do' them at all.
I suspect more people, women in particular, would be happier and more fulfilled if they put more of their energy into building solid friendships instead of just romantic relationships that don't seem to usually reap what has been sown.
I genuinely enjoy my own company, have hobbies, a great job, good friends, my own place to live, etc. I know by now that I am a better person when single than I am in a relationship; more ambitious, more engaged, more confident, etc. Don't get me wrong, I feel lucky to have been in my last relationship, as I had 7 great years with my ex, but that I als feel intensely lucky to live in an age where I can be so independent and so I had the choice to leave when the situation no longer worked for us both, rather than needing to desperately cling on to him because of some desire to conform or out of a fear of being alone.
