Fml. STD...

My bf cheated before I was pregnant. The bitch messaged last week "get checked for a bacterial infection it's not an std I got it, it's for the health of your baby" well doctors called today she gave me chlamydia and they called in pills. I just want to go kill the bitch. 
Edit: yes my bf has full responsibility. But the fact I'm pissed about is she told me she had "BV" and I go to find out it's an std. He already got his ass handed to him a few mins ago. It's just the fact the girl couldn't be more mature and say what it really was.
