Should I forgive him?

My boyfriend been searching up a young girl that used to live next door.
He knows how much I don’t like her because I was traumatised by the way my boyfriend and her were behaving with each other when she use to live there.
I got over it but now she came up in his suggested on instagram and I can see he searched her up.
He said he did it because she was posting stuff about voodoo and witchcraft and he’s sorry he did it and that it was ages ago.
Should I forgive him? Cause at the moment Im furious about it.
