hi this whole field of chlamydia is a bit odd some say it does and some say it doe's not have antibodies well he has either been playing away or he does have antibodies if these would protect him and not you and if he does have antibodies he could be a carrier. its a problem as he could have had it a few years ago and out its popped and you got it its that simple. this a couple of other sti's and std's are well known for doing just that and it could be up to 15 years they call the marriage wrecker's. do hope this helps in some way. good luck
is it possible for a female to have chlamydia and have unprotected sex with her partner and him not get it.? . i have been with the same person for 6 months and never cheated but i tested positive for chlamydia and my partner and i have had unprotected sex but he tested negative for it.
