Just because you feel poly, doesn't mean you can't be in a mono relationship. It seems like the relationship you in now is not where you are happy. If this bloke you just met seems like someone you could be happy with, maybe give it a go? If you find another person and begin to want a poly relationship again, you could talk to him about it when it came up? But live life for the moment I say! =]
I'm glad that it went well for you telling him though. I'm yet to come out to people really. I've told one of my closest friends and my ex-girlfriend who I was in a mono relationship with. I've always been in mono relationships too and only recently come around to my real feelings when I split with her. So in many ways, I told her because I felt she helped me realise. =]
