Search Results: sex too soon

I went out with this girl I worked with a few times, but stopped seeing her primarily because I need more time to move in from my ex. But I soon found out she still lived with her ex boyfriend, so major red flag.
Anyway, she came and left from the workplace over the next year, and she tried to be friendly with me again once she broke up again with her ex. But I got back together with my ex.
After a while, my girlfriend and I were about to breakup as she was Mormon and about to do a mission and I wasn't Mormon. Then the co-worker messaged me wanting to have sex again before she left to move to a different state.
I refused because I still hoped my relationship would survive. But after a month we were done. I talked to the co-worker for a while until she started going to the Mormon church too, and tried to convert me.
It's been two years, and I since rejoined social media and over the past year, my coworker never came up. I used a different email and everything.

But a few days ago, she came up as a friend suggestion with no mutual friends or anything. She even was the first result if I typed in 'm'.
After a few days she wasn't there anymore. But I'm not blocked.

Does this mean she's now checking up on me?

A good question for our days and even more for the future and far future is:
Why humanity still need male gender?
We now have machinery to do things, pretty soon we'll have also the AI.
The women in our days and even more in the future are independent and will be even more independent.
It is pretty clear that women, that really don't need too much sex, will keep the man around just for nothing.
In the future the men will exist just for themselves, a far different situation than what was until now.
If somehow in the future the reproduction will be done with artificial sperm (some successful experiments already happened ), the men will be completely out from the scene.
How do you see the future of the masculine gender in this context?
Should we expect to men to disappear? Will men become a myth of the past? Will anybody cry after that, or will be just a pain free unavoidable natural transition on the human path?
Is that something monstrous or natural and expected?
