Very I have to admit that I do not know your full story or how he has been interacting with you lately.
In your mind is this (HIS) contact a change for the better? Is there more of it? Is there interest on his part? Things like that.
Take some time to really figure it out, if it is better or worse.
If it is better why change something?
If it is worse?
Either address it, modify it, or last resort change it. I say last resort, because at times you don't really want to be dancing to their tune, if a change is still a GOOD change for you.
