<human>: My boyfriend [20,] got me into an MMO a month ago and I've been having a great time. I joined his TeamSpeak club/guild/company thing and have been hanging out with those guys a lot recently.

However one of the guys seems to have developed a crush on me. 

Various quotes from when I first met him. (Everyone else had left and he was helping me grind).

>Australians always have the best accents

> I was talking to [my boyfriend] and he agrees, you have like the perfect voice. Your voice is perfect

> You have such a nice voice it would make a guy want to go to the bathroom. 

*two minutes later he has to go take a leak* ...

He also gave me 100,000 in game currency. Then got really awkward about how he "felt bad I can't give you more stuff," as he didn't have clothing etc that matched my class. 

That was over a week ago now, but it never quite got that bad again. We've had a few deep chats - he's opened up to me a lot and is really struggling with a lot of things in life, including mental illness. So hanging out with him, even one-on-one over the internet doesn't bother me. I just don't want to be leading him on or hanging around him if it would harm him in the long run.

His crush has been confirmed by other people in the group, I don't know if he talked to them about it privately or what.

Summarize the given text in a few sentences.
<bot>: What are some tips or advice on how to hang out together with a guy crushing on me without giving him the wrong idea but being a cool friend?
