Political parties are inevitable with fptp elections. It will always come down to 2 candidates. Any 3rd candidate will only split the vote with whoever is most similar. People tend to naturally organize themselves into groups based on who they agree with most. I don’t know if its possible to get rid of political parties all together but having more than 2 would be an improvement. The only way to do that is to change our elections. Either ranked-choice voting or runoffs when no one gets more than half the votes could allow for people to vote 3rd party without throwing away their votes.
