Could you ever forgive your significant other if you found out they gave you an STD?

In this context this didn’t cheat they just didn’t know they had it from previous relationships and gave it to you

Any advice?

He lives in Italy and he got it before he came to see me in a different country and he goes back home next month. How do I trust him?
