Hi guys, need a bit of advice. Some backstory: about a year ago me and some other people found eachother in bad periods of our lives and managed to get a connection, so we formed a nice, bonded group of friends. So, one of the other guys, let's call him M, really likes this other girl, V. "Nice man, good luck." I say to him, since she's a nice girl and seems to like him back. Me and another female friend basically digged into this on his behalf to see if she really liked him back, and what we got is that she doesn't want a relationship. If she really wanted anything, she just wanted to have some fun around.

"Welp." I said to myself, and reeled the news to M. Said he would manage to remain friends. Long story short: he didn't.

Fast forward a few months: when her birthday came around, every one of us got together and pooled some money for a gift. M refused saying that he would do his own gifts and so he handmade her a make-up case, bought a bunch of other stuff (a lot of stuff) and replaced her phone's camera. I didn't even have the guts to ask him how much he paid. V was obviously happy and when we were alone she told me that she doesn't think M likes her, just that he's a nice thoughtful friend. He isn't, he generally doesn't care much. By this point I'm in pain for him because he isn't realizing how low he's stepping.

So after that, I basically understood that he's orbiting her, calling and talking with her and her mom almost every day, no idea what they say to eachother and I don't care tbh, while she talks to me about a guy she has a crush on, and how much she wants to "get chocked", sometimes appreciating me and my body and basically nodding and smiling at me and saying "same" whenever I bring up that I need just a f-buddy because "women are too much hassle". Me and V started to get close as friends because neither of us wants a relationship, so it's kind of implied that it would be more of a friends-with-benefits thing. As I said, she's hot, so I wouldn't pass up a chance (and we still didn't have one since we don't really live close) but M isn't taking hints that she's into him just for friendship. I mentioned the guy she has/had a crush on while he was present and he didn't bat an eye, talked about her wanting to "get chocked" and V herself brought up the fact that she liked when I said to her that I like her bubble butt. M didn't even flinch.

He's literally just present whenever she is, and almost disappears when she isn't. Almost all he does in social media is related to her, has her as his phone's background, and she mentioned to me that she once found a bunch of her exes in his FB search bar while he was screensharing.

Help me out guys, how do I bring him out of the hole he's digging by himself for himself. He's a good guy, I know that he took this path himself, but I really want to get him off of it. Sorry for the wall of text.
