He admits he misses england.. so why bolt?
You missed a lot. Harry & Meghan left the UK as the media there were relentlessly racist to her. Every day. So, they left England and moved to, at least, a commonwealth of the UK, Canada. Only, I forget why that didn't work. I think it was the inability to have security there. (Others can fill this part in.)
Now, they've moved down to CA. They hid out in Tyler Perry's huge home for a while. Yet, a couple weeks ago, even HE told a story about how he & Meghan talked, and to what depth they had a conversation.
All so strange and with all his rich friends and palaces, houses, cottages, estates.. nobody had a spare bedroom for Harry??
He can't stay in friends' homes as that puts an unwanted spotlight on the friends, with people prying to find more on WHO they are. The paparazzi would be camped out at their door, trying to dredge up details on these friends, and what's going on as he stayed there.
Also most people wouldn't have the room to house the amount of security Harry needs to have. About a year(?) ago, Harry complained that once he & Meghan removed themselves from active Royal duties, the UK government took away their security detail. He tried, unsuccessfully, to lobby to have the detail return, especially when he's in England, or a portion of the money given to him so he can hire his own security for him and his family.
Whatever his personal relationship is with the Royal family, Harry is still a son of a King and the brother of the heir apparent. For terrorists, who don't give a jot to read tabloids, the son of a King is considered a "high value target." Especially now, with all the conflict in Israel & Palestine and whatever side the UK is taking, Hamas killing a high value target of the enemy is a HUGE victory. Especially as Harry used to be in the UK military himself.
Back to the paparazzi stuff: last summer, when Harry & Meghan came to NYC, they made up this story about being chased in a high speed chase through Manhattan. (A physical impossibility here, with all the traffic and grid locks, meaning traffic stuck IN the intersections blocking traffic in all directions, every few blocks.) Yet, they were followed a bit by paparazzi. They didn't want the paparazzi following them to the friends' building where they were staying. They tried to protect their privacy. It was finally found out that they just waited the paparazzi out in a driveway near a police station.
When this made the news, they were given grief as they could have avoided it all had they JUST STAYED AT A HOTEL which knows the security protocol to protect high profile guests. Their security would have the extra rooms on either side of theirs to house themselves. They'd be allowed to be stationed at all entrances and on the floor they were on, and the hotel could hide what floor H&M were on.
Apparently, Harry finally learned the lesson and stayed at a hotel.
