Is it weird that someone doesn’t want to mess with me anymore because I’ve had an sti before?

He started off saying he wouldn’t judge me if I’ve had one before

I lied the first time and said I’ve never had one because I felt like he was lying about being understanding and was never going to speak to him again

We started talking about sex again later and I showed him my clean test results and told him about how I was infected with gon. almost a year ago and was treated and cured

Now he’s saying he doesn’t want to have sex anymore and I shouldn’t be mad because it’s my fault that I got an sti (even though the person I got it from lied about getting checked)

Then he proceeds to ask me for naked pics??

Is he being an asshole or am I wrong in a way I’m not seeing?
