Why won’t he believe me?

I started dating this guy end of November we have a crazy connection and chemistry, I went away few weeks to my home country and we continued to speak daily honestly couldn’t wait to get back to see him. Up until yesterday afternoon everything was going well or so I thought just after midnight he said he will message me in the morning to speak about something. This morning he tells me that he got sent a screenshot video from a fake Hinge profile which is clearly not me not my name but my pictures, what made it worse is that on the profile the person makes comments about gym ( I’m a gym girl ) this automatically made him lost trust and accuse me of going on there I’ve tried to talk to him but he won’t budge or listen it’s frustrating because I know the sort of woman I am I’m 30 I told him someone created that maliciously to sabotage what we have going on, just earlier that day he said he missed me. I understand he’s been hurt and has trust issues however it’s so unfair on myself knowing I did nothing wrong that he simply won’t believe me or acknowledge my feelings towards him. I simply don’t know what to do or say anymore I made it clear that I’m not on dating apps or anything like that clearly I want something serious.. what can I do or say? I really have feelings for him but making someone believe me for something I didn’t do hurts.
