The guy clearly is an underperformer that knows he cannot win through merit and instead wants to win by playing dirty.
Do not reward aggression towards you with attention and empathy.
You have to stay away from such people. The guy is likely someone with behavioral issues, bad personality traits and the undermining/sabotage could be a sign of a low skill workplace psychopath trying to manipulate and create a psychopathic fiction. You are not a therapist and it is not your job to fix that person.
When fire has nothing else to burn it consumes itself. Just don't add more fuel to the fire. Don't let that person be in your head, drain your energy. Do not ruminate about interactions with this person. Practice mental hygiene and focus on what's important: collaboration, your actual job, your goals, your friends and family, or something you can contribute in any way...
There isn't nearly enough information in OP's post to draw that conclusion.
