My two cents: It could be something to keep in mind, or it could just be that the more we get to know someone, the more things we see that remind us they are human. I mean, your past posts about him really made him sound almost perfect, but we know that no one is perfect. It's completely normal to find things about people that we don't especially care for as we get to know them better. I absolutely hate possessive men and what he did would be very high on my radar. But then, that's just me.
I would say to keep those possible red flag things in mind and maybe slow down a little. Maybe not so many phone calls every day, but again, that's just me. I once had a romantic interest that called me several times a day and then when we saw each other, I had nothing to say to them because we had already talked so many times. It was part of his possessiveness in that he wanted to keep tabs on me at all times.
