If you are aren't sure then you should wait and see if he says it to you first or wait until you are sure. You never want to tell a man you love them prematurely you are taking a chance of possibly ruin a good thing. Also never tell someone you love them if you do not know for sure that you do, it's better to be safe than sorry. I say if things are going that well he will tell you how he feels in his own time and if it isn't broke don't fix it. Remember that when it comes to love a maybe means no and if you are not able to decide and are having a strong gut feeling of maybe then it's not love rather it is attraction. Think about the long term and ask yourself whether you can stay with this person in the long term. Often when you get a mixed feeling then it's definitely not love because love is an emotion which can survive in the long term. You will never have mixed feelings about a person if you truly love them. You will always feel the definite yes.
