<human>: I've been with my girlfriend for three years now. She is pregnant with our second child. We have a 2 year old. She is 12 weeks pregnant and has been very distant for the last 7 months. No more texts saying she loves me or extreme affection like the first couple of years. Our relationship has been rocky with a lot of fighting. I figured it was being of the morning sickness and not feeling well.

It turns out she has chlamydia and she accused me of cheating on her. I have NEVER even held a hand with another girl in the entire time we have been together. 

She denies ever cheating on me and thinks she may have gotten it from either the stick they used for the ultrasound or a toilet seat. She also believes they could have mixed up her test results with someone else.

I have not been tested yet and plan on doing so in the near future. She was tested with out first child and did not have it. I also do not have any signs of having it. So I know she got it in the last year or so.

I really want to give her the benifit of the doubt but it's just hard. I really love her but cannot get this thought out of my mind. I can give additional details if you'd like, just ask.

Can you provide a brief overview of the text?
<bot>: girlfriend of 3 years recently contracted chlamydia and swears she did not cheat. I'm not sure what to believe.
