My Grammostola rosea (m 1 year ols) doesn't eat anymore

Hey guys I have my little Chile Rose Hair for about a year now, and the first 9 months seemed pretty normal. He ate every second week and was not that lazy...

But since about 3 months she hasn't eaten anything, I feet her everyday and put the cricket out after about 4-5 hours... Nothing I do seems to work...

His cage is in perfect condition (28°C and about 70%humidity) and he is pretty active when I take him out of her cage but not aggressive or anything.

He seems to look perfect (no damages or skin bruises) He never molted since I have him, so that may be one reason, but 3 months without eating seemes a little bit too long for me...

Maybe someone can help me

(Oh and sorry for my really bad english)
