STI PROBLEM

So I’ve had Chlamydia multiple time before I would always take antibiotics for it and it would go away. But my bf would tell me he doesn’t have it so we would have unprotected sex and I would get infected again. This last time I decided that I wasn’t gonna have sex with out a condom I took the antibiotics for the Chlamydia 2 months have passed I haven’t had sex since then but I still have a burning sensation after I pee and that would always happen when I had Chlamydia please help
