So my mans ex just recently messaged me saying all he does is cheat and that he’s using me and has Genital herpes etc...

I talked with him about it and he said he paid for me to get checked and he’d get checked to prove that he doesn’t have it. He also said that she’s crazy and is just lying.

Who should I believe...

She also said that he just texted her last week and sent her a video of him and a girl having sex

Him and I just started dating so
