Should I be Honest and Tell him after it Happens or should I keep it to myself ?

Yes I understand that but since 2019 he seems to be genuine . So do you think its too soon to do anything with him when we meet for the first time ? 

Should I give it sometime but what if the exact same personality is right infront of me the genuine guy I feel and talk to I should go with my gut right ?

You really can't know if he's genuine until you meet.  Whether you "do anything" with him when meeting is entirely up to you & your personal moral code.  When you meet in person for the 1st time, that will be your 1st date.  Assuming you do get to meet this year, the 3 years you have been "talking" since 2019 count for absolutely NOTHING.  This will still be your 1st date.  So if you are DTF on that 1st date & that is your choice, have a good time but be safe.

There's no such thing as friends with benefits, it's just a concept invented to make people feel less guilty about using others. One person is usually wanting a proper relationship and that person often ends up getting very hurt, and there's no benefit in that.
