Take it slow. Don't read to much into it. Like you said it sounds like he wants to test the waters with you again. A casual date can't hurt, especially if you approach it as a date with just a friend and not as if you are trying to rekindle your love or his. Then after the date you can see where things go from her.
Don't let him string you along though. If he decides that he wants o work on your R, then he has to cut of the OW and go to a C with you.
Best wishes.
