Stop having sex with this idiot !!!!!! === definately don't have his baby!
He can't love you if he won't even get himself clean of an std for you and himself.
Chlamydia can cause major fertility problems and if you keep getting re-infected from this jerk you may end up sterile and never have a child!
Chlamydia is a very easy infection to cure (you've done it 4 times already) but there will be a time when the treatment will no longer work.
Left untreated in women, it can also be a contributing factor in uterine/cervical cancer later in life.
