I guess I'll be the odd man out and say that I think you'd have to be pretty naive to stick around for a guy that's spending his Sat night with his ex instead of you. Being disappointed with that doesn't make you controlling, I'd say its a pretty normal reaction. I also don't understand why recent ex's would need to keep in touch so soon if nothing is going on? He needs to give it some time if he really is planning on moving on.
