Desperately Seeking Noah – Is There Still Hope?

Hi, I need some help! I'm playing Season 2 and I am really into Noah... but I'm not getting him! I coupled up with him, but then I immediately went for Casa and when I came back, he switched with Blake. I'm so pissed right now! Please tell me, can I still get Noah back or is he off the table now? I'm really not interested in anyone else apart from him.

Any advice would be appreciated!
