My semi LDR boyfriend of 3 months sent me $2000 so I could take an unpaid month off of work and stay with him in Texas where he traveled for work?

We’ve been pretty serious since the day we met, we’ve talked About marriage and the whole nine. We’re on the same page about our future, but I’m wondering (of course without having to ask him directly), is his gesture too much too soon or have you guys made gestures like this before, for the woman who was the one in your eyes? Thank you for taking the time to respond, if you choose to.

Forgot to add: in the same window of time he had also bought me a $400 promise ring from Zales. Is this too much too soon or green flags?
