I am falling in love with this man that I have been dealing with for a month and I do not know how to tell him what do I do

Nothing. Never tell a man you love him until he commits to you first.

It's never good to tell a man that you love him until you know for sure that you do. Since it's only been a month, I doubt you are truly "in love" yet. Love may start in the instant you meet someone, but it takes time to see it's full potential... you aren't there yet. And until you know if he's having similar feelings, I wouldn't recommend telling him that you love him.

Hopefully that will help you! :)
