Hello, please help me sort out this situation .

We were dating long-distance with my ex ( he's 30 and I'm 26) for nearly 3 years when he quietly disappeared after a conversation we had where I playfully told him that I didn't care if he were to leave for another woman . I've always had a pattern of playing it cool with him because I've been scared of showing vulnerability . After that day though, we were broken up for 10 months since he never really said anything but quietly disappeared. He's an avoidant who despises conflicts . I didn't pursue him but made sure rumors got to him that I had someone else, only to hurt him the way he hurted me . Two months ago though we got back in touch  and he apologised for the way he went off the radar. I asked him some help with a project when I'll be back to my country and he showed enthusiasm and support, even making inside jokes.
Knowing he's also single, I confessed after that I still loved him and told him all the truth about having been single for the past months  but also lashed out at him, telling how he broke my heart . He never responded to my email.

In 3 months I'll be back in my country. Should I let him know I'm back or just leave things this way ? I can't help but feel like there's an "unfinished business".
Thanks a lot and sorry if there are mistakes, I'm a french speaker .
