Husband of almost 5yrs completely blocks my calls after a conversation where he made an assumption that I lied

Hello all, I'm currently in a situation with my husband, where he has me blocked currently 4 days and counting. After he made a assumption that I lied about there being no hot water in my apartment ( we live separately but we're around each other until that day) I live in a complex where at times the water does go out but the storm we all pretty much dealt with caused a issue, this particular day I told him about the water no issues and later on still no hot water, I called him later that night now he's super upset cause no water, at which point he was really digging in the situation I'm gonna have a talk with the manager there ok no problem, hours on the phone I go check the water and it was getting lukewarm mind you I didn't check for hours but I will say the heating company was out that day working on it they fixed the problem and come to find out they forgot to light the pilot at which point the matinence manager came out to light it up,( this is what I'm told by neighbors also I have a photo of the heating company out that same day) needless to say but yup he said you had hot water all that time or at least that's what I was able to make out of it before he hung up on me and blocked me. Here we are to day and I'm kind of struggling with what one would call unresolved issues in respect to that, I cant get ahold of him at all, I find myself missing him I guess beside myself and nor in the best mood, what do you guys advise? How long is to long with being blocked? And my thoughts are really bothering me because I have no idea what to do in respect to this, I feel confused, lost and overall betrayed, I apologize for the long post
