The right thing?

I have been in a long distance relationship with my boyfriend for over a year now so when Covid hit and he had to fly back to his country I was scared but confident that we were gonna be ok as we’ve been doing long distance for the majority of our relationship. After 5 months I finally flew out to see him and had the most perfect 2 weeks... until I saw that he had been texting another girl for nudes both receiving and sending them. I immediately flew home as I was so heartbroken but after 2 weeks of being apart I’m flying out to see him again and he’s trying to fix his mistakes as I know he’s truly sorry for what he’s done. Am I right to give him a second chance?
