On the subject if questions from friends and family...
You may need to repeat yourself several times over a period of years.
People want you to be happy. People also perhaps don't understand the quality of the man market. So to them, it's hard to understand why you do not simply find a lovely man.
When people see you happy and busy they will ask less.
Repeat yourself firmly and confidently. Something like "that's not on my priority list right now I'm too busy doing x and y". Avoid defending your decision...it's not something you need approval for. But also avoid huge sweeping statements such as "I will never ever go on a date again so long as I live" because that does invite challenge.
Over time all my lived ones can see I'm having a blast and simply much, much happier than I was in any relationship.
The only people who still raise it are my Internet dating obsessed long term single friends because honestly I think it threatening to think that I reject all that. They meet a series of lovers and liars and I sympathise and give advice so to me it's hilarious when they suggest "would you not want to give it a go".
That brings me to your second question as to whether I ever miss having a partner. Probably for around 15 minutes a month on average. But what I miss isn't reality...it's a man who doesn't exist, or a real person with invented behaviours and values.
I consciously value and appreciate my freedom and spontaneity. And I look back and see how curtailed that was in relationships. But that has taken some time....it's ok to be wistful or curious. You don't need to make a decision forever, you just need to say, I am going to put myself absolutely first this year and I'm going to live as if I'll always have that privilege.
If something happens to change your mind that is ok but i think fir me it was onky by thinking of a long period of time solo that I really started invested in big exciting solo plans and lifestyle changes.
I see so many women put life on hold because "I might meet someone and then he might have a cat allergy / might not like camping / might not want me to go to Costa Rica for a month/ might be put off that I'm a pro weightlifter"...so they just sort of languish and give off these sad and uptight vibes....
Which takes me back to my first point, when people see you doing great stuff that you love they stop thinking that a boyfriend would be an improvement. They start thinking about shaking up their own lives. A hell of a lot of coupledom can be about routine, reassurance and resentment.
