Tell me what’s going on?

So everyone I have a question, say you have a boyfriend of almost 2 years and let’s be honest it wasn’t an easy 2 years. One day you’ve had enough of certain things he did like going on road trips without so much as a text about it, up until he comes back. You finally tell him how you feel being treated this way and over night he makes drastic changes to his personality and lifestyle. I mean a full 360, he literally converted to a Christian and is making a lot of changes to both your lives. What do you consider this behavior to indicate?
