maybe he has some personal stuff that he has to deal with first? for example I have a friend that I've known for a very long time and I vent to them very often and one day they haven't been on for a YEAR so I think I was being too annoying and they left me, but yesterday they texted me that they had some problems because their technology broke and had to buy a new one but he is just two day so maybe taking a break from technology or just busy for a few days
