DeletedUser349 So, have any of you been able to work through this issue with a significant other? Did you do anything to resolve the issue? What was the result?
Yes, I have. We had been using iMessage for quite some time back then and we all had to adapt to use Signal instead (I even managed to convince some of them to use SimpleX). The all accepted the change because it was important to me and so it was important to them. I supported them during the transition and after and now, about three years later, iMessage is an ugly thing from an unpleasant past.
In my opinion, anything thats important to you should also be important to your partner. The two of you should respect and appreciate one another enough to work this out - in the end it's really just about colors. If you cannot get past that, then maybe there are bigger underlying problems in your relationship. You should deal with those first before you ditch your iPhone.
