I haven't heard from him in about 4 hours now going in today. When he is sober I hear from him every hour at the least.
To me this is a bit concerning. I totally get it that you both perhaps feel a need to connect frequently each day. But every hour seems a bit excessive to me (if it were me). However, if texting or something that keeps you in touch with each other is agreed by both of you something you really need and something you want to do. Each couple has their ways of meeting needs. Maybe he is just busy; maybe tired; perhaps bogged down with work...and the list goes on. I wouldn't take his not contacting you every hour personal or that it is a sign something's wrong.
Please feel free to share more on this, if you want....we are an understanding bunch. I'm fairly new here myself, but so far this board has been a tremendous help!
