<human>: Give me a shortened version of the text

I [f20] am paranoid so will try to be vague about some of the personal details, but basically I've been friends with this guy [m25] for around 6 months now. Started out as online friends with a shared hobby, started texting more, and for the past maybe 5 months would literally text all day and be enthusiastic towards each other. 
He's visited my city a few times and we hung out, very fun, and we have had a discussion about our mutual feelings of attraction, and want to spend time with each other more before we "date", this was the last time he visited. That visit we actually had "fight" almost? I was upset at him, but we ended on a very nice note.

We have made some attempts to bond outside of texting (do something together over skype) but the last couple times weren't as fun as they'd been before.

Before that, some stressful things have happened in his life, and I've been feeling insecurity myself because LD makes me very insecure. Now recently he's told me he's been feeling depressed (lost job) and battling with some emotions lately. So alright. 

My concern is, for the past week, we don't text as much, a few texts a day sometimes even. He's been immersing himself in the hobby with his buddies for any free time he has, and just doesn't seem interested in me for the time being. He also ignores it when I inquire about what's making him upset when he says he is, and he used to share that stuff with me. 
I want to bring it up to him but don't want him to think I'm clingy or something and I'm afraid of the possible answers.

My question is this: Should I be concerned? Is he doubting what we've got? Or is he just dealing with stress in a guy way?
<bot>: Guy is withdrawing from me and has had some stress going on in his life. Not sure if he is over me or just feeling down.
