I had chlamydia they gave me 6, pills and they gave my parter 1 pill? Why.? Is it because he a man? And would that one pill cure him?

Data missing. Numbers can matter but it would help if you give the name of the medicine in the pills. It does make a difference. You are welcome to start over.
6 pills same? Actually to treat chlamydia you need 1g of azythromycin. 4 x 250mg of azithromycin. When treating chlamydia its a good idea to also treat gonorrhea concurrently. Your doctor may have treated you for both. Your partner may have received just 1g of Azithromycin and was not treated for gonorrhea!
