<human>: Can you summarize the given text in a few sentences?

to start, this guy and i do have casual sex BUT we are close friends as well and do platonic activities too (playing video games, going out to eat, hanging out at home, etc). he is a big fallout fan and has a large gaming laptop he uses for school, so i bought him a fallout-themed computer bag from the Bethesda store. with shipping the total came out to about $80. last month for my birthday he bought me $70 gaming headphones and took me to a fancy dinner ($140), so i really wasn't expecting anything for Christmas.

but yesterday he surprised me with a new 3ds xl with a game and accessories, totaling about $300. i accepted it and have played with him a bit (he has one too) and I'm really enjoying it. I'm just confused as to his motives here.

we've discussed a romantic/dating relationship and he's adamant that he does not like me romantically and isn't interested in dating. but to me it seems crazy to spend that much money on a friend, much less a fwb. he's even said he doesn't want to do certain things during sex because they'd be too "emotional" or "coupley". in the past he's said I'm basically his perfect girl, but something feels "off" or is "missing". maybe *i'm* just missing something here, but i can't read into what his actions are saying.
<bot>: male fwb has spent copious amounts of money on me, a girl he insists he doesn't like romantically.
