Do what #1 said. However it is also worth noting that at least for me and every other poly person I know, there isn’t really a ‘leave for a better person’ thing, and communication is far more required in poly relationships than in others. He should communicate with you and you should have information to discern whether you actually need to worry or not.

tbh if you have jealousy issues i think a poly partner is not for you. speaking from experience there will always be that niggling feeling that you aren’t enough, he likes someone better than you, that he would rather be spending time w/ someone else, etc.
