Wrongly accused by boyfriend - what to do?

I'm in a relationship with my boyfriend. We have been dating 8 months. We both saw a future. We recently travelled overseas for about a month and did so successfully. That is, our relationship has been tested under stress.

But now it's under immense stress.

This is a long distance relationship. We visit each other once a month and we're only accessible by a one hour plane ride.

My boyfriend uses a gay chat app to connect with the gay community because we are both closeted. We are both exclusive and I trust him.

Lately, my boyfriend found that he was being impersonated on the app. Apparently someone has been distributing a picture of him asking people if they know him. They have also, apparently, been found to be 11 metres away from where my boyfriend lives. So that person knows the whereabouts of where he lives. Also, this person has been flicking between 11 metres and 750 kilometres, which is equidistant to where I live.

The issue is that my boyfriend pointed his finger at me. He accused me of something which I would not do. I feel hurt, angry, and disappointed.

That night, I had a mild asthma attack/panic attack. My father was rushed to hospital due to his deteriorating terminal illness. I was meant to drive to hospital to be with him, but instead, I was seeking help for my breathing difficulties. I called my boyfriend for his support. Whilst driving, I was told that I should come clean, tell the truth, not play games. He said that he did not believe my father was in hospital. He told me to go home because my father wasn't ill.

I drove erratically to the hospital, crying, and gasping for air. My father was dying, and my boyfriend had just accused me of a wrong.

I did not commit the said act. But he remains adamant it was me. I tried comforting him and telling him it wasn't me. He panicked and called the relationship off. I was hurt. He then took me back in a few minutes. Now, we are in a state of minimal contact where he wants space to think things through.

I don't know what to do. I didn't impersonate him; he doesn't believe me.
