Well I think she was already friends with the guy for awhile now from what I saw on FB. About her age, 40 or so. He wasn't ugly though, but he wasn't built and didn't look like some of the hunks that post here. He had a sort of Beta cuck look to him. Not nerdy just the type that throws money around to impress. Looks like he just retired from the airforce after doing his 20 and is a real estate agent. So he gets his 20 year military pension plus his real estate job money. So basically probably taking advantage of him for his money since she's a teacher in a public school and with the pension plus the houses he sells he must make good money because he sells a lot of houses from what I saw on his FB page.
What you're doing in this post leads nowhere, believe me. First of all, you're watching the whole thing through a soda straw (Facebook). You have no idea how she really feels about him or what he's like. You're basically hamstering over something, AND subsequently comforting yourself by rationalizing that he's this way or that way and ergo she wants this or that instead of you.
Simply put, I don't think it's productive to 1) follow these people's activities and 2) frame your circumstances based on what you're seeing. I recommend not following women you've just begun dating, for starters.
To expand on my take on flowers, like most things it depends on anyone's mindset and personal frame. Are you doing it with a sense of abundance and giving value? Or are you trying to negotiate desire or "be nice" to convince her? (Not you, I mean anyone.)
Once a man is strong in his mindset and true to himself, he can do what he wants since he's not worried about the outcome. I still wouldn't recommend sending flowers that early if asked for advice, just as a rule. But if someone were asking that means he's not in the right frame of abundance and self-value.
As a man, once you've achieved this level, the rules for what seems strong vs. weak (alpha/beta, call it what you like) become largely irrelevant, because you are doing what pleases you, and willing to accept (or even ignore) a multitude of outcomes.
