Brumating for 4 months. Is this ok?

My beardie went down october 15th and is still down (feb 17th). He's only eaten twice that whole time. I lured him out with a horn worm those 2 times just to see if he would be interested, he was and ate them, then he basked for a few mins and went right back to his hide.

Should I let him continue brumating or should i bring him out, make it a point to set him on his basking stone to try and get him feeling hungry again?

Picture from last summer. I miss him.
