I tested positive for chlamydia but my girlfriend didn’t
I’m kind of lost on this whole subject so I’m looking for guidance. 1 year ago I (21M) got a test for chlamydia and my girlfriend (21F) did too after seeing that my test came back negative. We both went through the treatment. After 6 months I went to get another test as that was recommended it came back negative. Then just 6 months after that I got another test as my urethra was very itchy. It has just come back positive. My gf also got two tests and they came back negative. There hasn’t been any infidelity from my side of the relationship so I’m just looking for advice as to what could have happened? Currently my gf is skeptical of me cheating on her. I would really appreciate anything!
TLDR; My gf and I tested positive for chlamydia went through the treatment. I did another test 6 months later came back negative. 6 months after that mine came back positive hers did not. She thinks I cheated on her.
