[Avengers Endgame] Any idea what happened to old man Rogers?

Is there any information or speculation as to what Cap did after he handed off the shield to Sam? I'm sure he had kids. Did he say his goodbyes and come back to the main MCU timeline permanently?
Did he come to pass on the shield and say his goodbyes? Going back to his family in the altered timeline? CAN he get back?

I always assumed he had enough Pym particles to go back to the alternate timeline. This of course raises about a billion problems like:

Did he just sit and watch all of the worlds bad stuff happen in real time or did he do things differently and create a different timeline all together?

What happened to that timeline's Steve Rodgers? Did he get un-iced? Did Steve just accept that or let it go?

Time travel fucks everything up, no matter what series you are in.
