Relationship and Tinder problems. Should I talk or should I just leave?

Hello everyone, so recently I found a message to my boyfriend from Tinder which says: Thank you for your Gold Tinder purchase ( it was a date, price, confirmation code, expiration date)... I still did not say anything and it's been a while. Should I start to talk before I will leave or just should I pack my things and go? Thank you for answers

If I will talk I know already what he gonna say. In the beggining he will be defensive. After one day he will say that it's a spam. Before me he had Tinder and they still sending advertising messages or emails. But it was Gold membership purchase. 13 days ago...

If anybody interested how this story ended up... So I told him that I know everything, of course he became very defensive ( from his reaction I actually understood that he might knew that I know everything. Probably noticed my weird behaviour and noticed that he forgot to delete those emails from tinder). And of course he said that he purchased this not for himself, but for somebody else. And like he said: it's none of my bussiness what he is buying for his friend :)
