What should I do?

So theres this guy I’m seeing but on his bebo he writes that he still loves his ex ): tonight he tried to kill himself I wasnt there but my friend rang me, hes at the police station as we speak but I cant get there ): It made me realise lifes too fxcking short, so I thought I should tell him how I really feel, im thinking of writing a note:

Liamm, I know you love bridie but after the other night realise that lifes too short to keep things bottled up. Everytime I see you my heart skips a beat. When I’m with you I feel like I’ve never felt before. If only you felt the same. I know you dont and I guess I’m okay with that. I dont know how I survived without you before I knew you; and I know I cant if I lose you now. You mean so much to me if only you knew.

I love you Liam

What do you think? Should I write the note and slip it in his pocket next time I see him or will this ruin we we have got?

Please help thank youu
