Your words are a little confusing.
You contracted Chlamydia from a partner in October 2011 and you were treated. However, your discharge, which you associated with Chlamydia, hasn't dissipated?
Is this a new boyfriend or an old one? If it is the same one you had unprotected sex with before Ocotber 2011 than it is entirely possible ducky is right and he has reinfected you with Chlamydia.
If it is a new partner and you were cleared of Chlamydia than your discharge could be something else. If you weren't retested for Chlamydia and told you are cleared I would ask your gyno to test you. If it is Chlamydia still than you and your partner need to be treated, as ducky said.
Good luck!
If your partner hasn't been treated for chlamydia too then yeah he has it and is probably reinfecting you. You both need to be treated simultaneously to stop the infection. I recommend you telling him that you had an STD infection and he should get diagnosed and treated too.
