HELP PLEASE NEED ADVICE!!!!!!

So one of my best friends (we will call him bob) has recently been dumped. I’ve had a crush on bob way before we were even friends. And within the last few months, we’ve gotten really close, he’s like my rock and he’s the person that I can trust and tell the deep stuff too. About a little more than a month ago, he got dumped. I’ve never met the girl that dumped him, and she dumped him because of distance. So Bob has been really really bent out of shape about this breakup. I really really care about Bob and I hate to see him like this. I try to offer him advice but I don’t feel likes it’s helping him at all. Also, since I care about him and worry about him, I’ve tried to talk to him everyday. It’s been a month that I’ve talked to him everyday and I don’t mind at all because I care about him. So yesterday, I texted him, and immediately he was just like “Hey, I’m not in the mood to talk today, I’ll text you when I am I guess.” So I just responded and tried to be understanding and said okay I’ll talk to you later. It’s grown into a routine that I talk to him everyday and it feels weird because I haven’t, and I’m also really worried about him. Should I wait for him to text me within the next few days? I just don’t know if I can, also part of me feels like something is wrong and there’s something he’s not telling me and I’m just really worried. If he doesn’t text me within the next few days, should I text him? Or maybe I’m just overreacting to this whole thing, I just really care about Bob and I know he cares about me.
