As a serious reply to this, if you can get her to come back and give you one more chance, you might try this. @catweasel has given you a reply here. I am his wife -- and we are both crazy about Steemit. But sometimes it's just essential that we talk to each other. We had this problem (not over Steemit, but over him not answering his phone when he was away from the house -- sometimes because he didn't hear it.)
So we got a cell phone which is just for the two of us. Before he leaves the house we make sure he has it and that it is turned on. When it rings, he knows it's me and will answer it. This has saved us both a lot of anxiety and grief.
When you get on Steemit, have your phone right beside you and make sure it is on. so when she calls you will hear it. And when you hear it, answer it. Take it with you to the bathroom if necessary. (Don't dwell on that image.) She needs reassurance that she is important to you. If you really care about each other you can find a way to make this work.
If she simply doesn't want you on Steemit ... that's another matter (a control issue. You may want to rethink this whole situation.) But if "missed calls" is really the heart of her complaint, you can reach a compromise that works for both of you.
On the other hand, I have stopped seeing certain "friends" because they couldn't leave their damn cell phone alone long enough for us to even have lunch or dinner together without us being interrupted three or four times during the meal. To me, that is simply rude.
So, I understand this problem from both sides and I can sympathize with each of you. I hope you manage to work this out. If you stay together long-term, this is only one stumbling block (and a pretty small one actually) you will confront. Practice finding a solution you can both agree works for you. Best wishes to you both.
Thanks dear. I'll keep trying . Right now she's still not yet back but hopefully we'll resolve this ... I appreciate the concern of you and your husband. Thank you!
