Im inlove with a man...but he has gf please help me?

Does this man love you? Maybe he does but not enough for him to stay away from another girl. He does not love you enough to wait until you say you love him. He is not sure if you love him too so he just kept going with his relationship with this other girl. This kind of guy does not know how to love truly, he is just someone who wants to stay on the safe side. Therefore, I suggest you just let him go. If he is capable of leaving his current girlfriend for you, how sure are you he wouldn't leave you for another.
