Being Me, what is there to lose? All he can do is keep on ignoring you, same as now but you will have the experience of trying something new. You can feel good about yourself. I know in my sitch I often did things because I wanted to know I'd done everything I could, good results are a bonus! As Aud31 says "keeping quiet is a cheeseless tunnel". My only suggestion is to do it nicely, in a calm and upbeat manner. Tone is very important, it can make or break most interactions. Good luck.
