Does he know why you're with him? Seriously. Do you think he knows all the reasons why you're dating him? Clearly, it's not because he does well financially. Because this dude is being insecure, and is probably trying in a tacky way to remind you of his value. Many men measure their value in dollars. This is just the way it is.
Why are you with him? Is he funny? Supportive? Does he make fantastic French toast? Let him know why you are into him. This might curb his obnoxious boasting.
I dated a women once with really large breasts. Now, I'm not picky about boob size. When it comes to hooters, I'm an equal opportunity enthusiast. It's like having to choose between birthday cake and cupcakes. I love them both. She would talk about her gazongas all the time. All. The. Time. Even to friends. She'd crack jokes that would draw attention to her boobs. I was not with her at the time for her chest. Her sweater pandas didn't even really figure into why I was attracted to her. Poor chick was so insecure, she was convinced that her boobs was the reason dudes wanted to date her. Maybe there were dudes who dated her because of them. Not this guy.
Lovingly tell him that his bank account is of no interest to you. That his bragging is really embarrassing and that you love him for him. If that, in fact, is true.
Sweater Pandas! I love it!
Ego stroke, my uncle is like that. Inflated egos are just awful when they are popped.
You're a darling, JDV...
I totally agree. He sounds very much like he can't understand why you would like a guy like him.
We all can get into modes like that and our fallback is always the one thing about us that we are most sure is really, really good. In this guy's case it's his money.
In my case, I tend to fallback on being weird. When I'm insecure about things I'll tend to be more "pointed" about my weirdness. When I'm secure, I simply do weird things without thinking about it. (Like literally skipping down the aisle of the grocery store with my daughters.)
