Boy 1 is a user. He wants all the benefits with none of the commitment. He will drop you whenever it isn't convenient for HIM.

Boy 2 is actually showing some respect and interest in YOU.

Now Boy 2 is on the scene, Boy 1 is getting possessive because he is losing the 'good thing he has going at no cost to himself'. If you dropped Boy 2 then Boy 1 will just revert to using you again.

So... I think you would be wise to give Boy 2 a chance.
