How do i know if he luvs me?

My boyfriend, Kyle, acts like luvs me...but i dont know cause he never says he does (i ALWAYS tell him i luv him...cause it is the truth!). I know my BFF's pword and e-mail 4 her myspce so i always go on her account and talk to Kyle. I always ask him if he likes or luvs me...but he nvr answers...he always changes the subject!
