Search Results: is he ever going to talk to me again

I've been trying to be friends with this guy for a year now. He's a friend of 2 close friends of mine who are a couple and we always have dinner the four of us. When we met, he was going through a very hard break up (it was recent and she had even threatened to kill herself) hence he goes to therapy.

A year later, he's much more relaxed and open. But what has always bothered me is that he doesn't seem to want to develop a friendship: he doesn't want to hang out (neither in a group nor alone unless a close friend of his will be there). Now, I have to respect this, even though I don't understand why this is.

Sometimes I think he doesn't give a crap about me but when I invite him to important events in my life he shows up without hesitation, and he invites me to be a part of important events in his life as well. He even replies long , important texts with long texts. And whenever we see each other, he'll ask about things I told him the last time we saw each other. I mean, any other guy wouldn't do this if he genuinely didn't care. He even organizes for us 4 to hang out, so, again, a person's niceness can only go so far, meaning I don't think he's just being nice.

I don't think I've ever given him a wrong impression because I've asked him to tag along in group settings 95% of the time. So, I just don't think it's related to him 'thinking I like him so he distances himself'.

I seriously don't know what to do. We're clearly not on the same page. I'm interested in getting to know him as a person, but he puts up this barrier. I don't want to look like the 'clingy' one. I don't want to invest time nor feelings if it's going to be for nothing. If I talk through with him it'd have to be over text, which I don't want to cause I hate talking these things through text. And I just can't wait any longer cause next time we get to be 5 minutes alone could be I don't know months from now.
Should I throw the towel or wait and talk it out?
