Positive in Past, Negative follow ups, boyfriend positive for chlamydia

Unlike most of the threads here, I have a slightly different situation.  

In April of 2009, I went for PAP test & STD testing.  I came back positive for Chlamydia in which I was prescribed Azithromycin - 4 500 MG pills.  I took these as one treatment.  On May 22nd, I went in for follow up testing, and resulted in a negative test.  I proceeded to have a 2nd follow up test done on June 22nd, and once again, received a negative result.  Let me add, one was via swab and one via urine sample.  Needless, I met my boyfriend in the middle of these two tests.  We did NOT have any sexual contact until after my 2nd negative test.  Needless to say, my boyfriend had a blood test done at his doctor and got the results back today, testing positive for Chlamydia.  He claims to have been tested 2 months ago and everything was negative then.  (Added:  I am unsure if he takes any medications and know he has told me there is a history, even recently, of having taken steroids.  He claims to have only been with 4 women plus me, 5 total. He also claims to have never had a STD prior to this, so he is hurt because "he got it from me".)  

I am going in tomorrow to be tested and treated as well, but I don't think this came from me.  He says he has been tested since his last girlfriend and since he has been with me.  Right now, it all lays out that he thinks I have been cheating - has not said this, but I can take a hint.  

Anyhow, what my question is - If he has been faithful, is there a chance that with my testing negative he still contracted Chlamydia from me?  If yes, then how would 2 follow up test comes back as negative for me?  I am lost on this, and want to believe that he has been faithful.  

As pointless as it seems, I feel that our relationship is on the line with this.  I requested a copy of my medical records stating that I was clean on both 5/22 and 6/22 to prove to him that I did not carry this into our relationship.  Tomorrow, I guess, will be the true test.  If I test negative, I will know that it has come from him and will need to question how to proceed in my relationship - although, I cannot end it completely, as I am pregnant with his child.  I also must add that I have my doubts any of this is even true.  I am curious if he is coming up with some crazy way of ending things with me (???) or if it is to test to see if I have been faithful.  

And it has come to my attention that you cannot detect Chlamydia through a blood test.  Is this an accurate statement?!?!?!?!?!  

Thank you for any insight!  It is truly appreciated!

If ever you had chlamydia, a blood test would detect it.  BUT it could have been a past infection that had since been cured.  Blood test doesn't tell if it is a recent infection.  Tell your boyfriend to get a urine or swab test for chlamydia and go from there.

Thank you.  I know that it will show if we have had it in the past - what he is telling me is that he has tested positive for Chlamydia via a blood test.  As of this moment, he has not told me he has been swabbed - Which goes to my idea that this is all just to get me to admit I have been unfaithful, which I truly have been.  

I plan to get tested tomorrow anyways, not only to clear my name, but to clear my health bill and protect my child!  

Thank you!

Well, that is good.  But just so you know, they test you for chlamydia while you are pregnant.  This is to make sure you don't pass anything to the baby during childbirth.

You have not read my posts on blood testing for chlamydia. It should never be done. Disreguard all of your boyfriend`s blood tests. If you want him tested use the urine NAAT test. I don`t think you need retesting.
