My ex lied to me and gave me an std?

So me and my ex were tryna make a go of things again and we went away for a night and He didn’t want to use protection as he doesn’t like wearing it. So I asked him as he been with anyone since me and he told me no and he swore on his nanny’s life.
I trusted him.
And now I have a std I then texted him to let him know what he gave me and he told me basically to F off.
And I told him sorry but I thought I should let you know he’s in denial and doesn’t want to believe he has anything.
I’m gunna get treated on Tuesday and said if he would like to come with me he’s more than welcome and honestly I shouldn’t even offer I feel like I should be mad as he gave this to me.

But I think it’s terrible he won’t do anything about this now and will continue to spread it around to other women
