Lavender,
From what I hear, I just have a gut feeling that something is off with him.
“He asked his rabbi if he can give me his number but the rabbi said no.” That sound to me really weird. What’s he or his rabbi afraid of?
“He is 30 and already lived in 3 different countries on his own.” Sounds a little unstable.
“it seems he didn’t really have relationships before either, except one, who turned out to be crazy.” – At 30??? Sounds immature socially. BTW it takes two to tango. Saying that she was crazy does not bode well for him.
“He is 30 and already lived in 3 different countries on his own. So he didn’t sound immature or someone who can’t make decisions without his rabbi. ” But yet he did. Again something off.
Lavender, consider yourself lucky.
