Me and my partner have been dating for 10 months and he just now told me he found out about him having chlamydia. He says he got it from the girl he dated before me, and i want to give him the benefit of the doubt because he told me the girl he was dating before had it way before he told me to get checked. However, when he first told me she had it, he said he didn't. But now he is saying he never got checked and said he got it from her. I have had no symptoms down there the whole time we have been dating and i feel like if he had it from the jump like he said i would have. I want to give him the benefit of the doubt but i have to know. Is he cheating?
