The practical route would be for Meghan to wait a few years before bolting. However, her history doesn't show someone that is thoughtful or patient about her plans. She has plans, many plans, but if you look at everything she has done, she moves fast and never looks back. She is a shark.
I think she is still "love bombing" Harry for a purpose. All the articles this week about how they're still so in love, blah blah blah, is to keep Harry in line and unaware of her plans. I think she's already looking past him towards the future. Unfortunately for her, true obscene wealth isn't going to happen if she's on her own. She will need to remarry; for money. Again. There are many single billionaires right now. Elon Musk and Bezoz to mention 2 age appropriate ones, both single even if in relationships. Both ego maniacal enough to enjoy "stealing" a Duchess away from a Prince. Men love to brag about tit like that, "she left a PRINCE FOR ME!!" So I could see her trying it. Many Arab/Middle Eastern/Far Eastern billionaires too. And of course, if her stomach can handle it, there's usually some wealthy geriatric around.
If she goes the Arab route though, she better buckle the duck up. They are very formal and very few of their wives have many of the rights Meghan has enjoyed thus far.
Do I think she loves Harry? Or ever loved him? NOPE. Love isn't removing your person from everything they always held dear. It isn't tearing up a sibling relationship that was plainly close. It isn't embarrassing him by disrespecting his family. And it sure as duck isn't keeping your child in another country and doing pap walks that you know would upset him based on his bleating about his lifetime of trauma induced by paps. I hope she loves Archie, but frankly, she hasn't shown that she loves much of anything beyond herself.
Thank God the Queen didn't capitulate to her buyout demands. I'd bet Diana and Fergie both had to sign NDAs. It's pretty standard. Meghan will likely have to sign one too. But if she's on to greener pastures via remarriage to a wealthier man, I doubt she'd need to spill the beans to fill her coffers.
I'm hoping Harry is a handful with her. That he is as hot headed as reported and gives her a huge hassle. He has the security on his side so hopefully he'll have a massive tantrum, grab Archie, and bolt.
