This is probably dramatic. But oh well
My husband worked the same job for 10+ years. At this job he could text all day every day. We had a flow of text convo all day.
Now at his new job his phone is in a locker for 8 hours. Sometimes he'll send a text during his lunch but usually not.
3 weeks into the new job and I feel so much distance between us. No convo while at work. When he gets home its just chaos with our toddler and baby twins. By the time we go to bed we've hardly had a conversation. And then it starts all over again the next day....
It's not dramatic at all. You have both had a massive change in dynamic and I can imagine having those texts from your husband made you feel less lonely. He may have even supported and rooted for you through texts. Not having that is a huge deal. If conversing is really important to you, maybe try and take some time before bed to really catch up. I know it's going to be different to what you once had, but over time you will find a something new that will work for your relationship.
