I'm going to be honest with you: I can see why Musk and Grimes are attracted to each other 100%. Out of 10 points, I give them an 8.5 out of 10. It's very easy for them to connect romantically and intellectually. They have a lot in common with each other in terms of money and home life, as well as strong signs that this was meant to be a long-term relationship.
However, that doesn't mean that they'll stay together for the rest of their lives, especially because there are some very intense astrological aspects in their birth charts that show that they won't be supportive when they try to achieve their own personal and professional goals. Because there isn't as much of a synergy around career support, this shows that their separation is because they don't want to be too close in this area.
