Hi, T.,
Co-sleeping is NEVER a good idea from the get-go! We learned that the hard way.
You will have to be persistent with this one! EVERY SINGLE TIME he comes to your bedroom, one of you must get up and take him back to his room...EVERY TIME...DO NOT GIVE IN TO HIM. If he cries, etc., tough, let him fuss. He may even cry himself to sleep...in HIS room!
This will take some time & you will both lose sleep, but well worth it in the end. You & your hub need your "space" back; it's long past time.
Good luck!
