Convinced my gf to DCA with me for our future

I convinced my gf to DCA with me for our future and for our kids. She says she has no idea how to handle it or how to buy BTC but she is interested in it. I also told her this will be used 5 to 10 years from now.

Now our monthly DCA combined is between $800-1000. Time to get that Trezor 3!

PS. No issue if we are ever going to break up, I will marry her soon.
