I guess im falling in love

Well, I meet this guy a while ago, about a month or so... and he is always super cool, every day asks me how im feeling, what ive been doing, flirts w me, say im pretty and all this shit The point is: I break up after a 4months relationship a month ago (may 12). We meet at may 30, almost a month ago too. And i dont know if he feels something for me or is just this flirt thing, yk? He's almost 10 years older, treats me like im a princess, never tried to ask for a nude or take advantage of me, hes super kind and lovely. He look really interested in whatever I bring up, every time... But: I asked my friend to add him He added her back He sent a text (nm, just saying "hey") I told her to flirt w him He flirted back He sent her snaps, the same ones he send me (so, he sent it in a roll) I dont know how to feel about this. Bc we have nothing. Isnt a relationship. We dont have anything at all. We flirt sometimes and thats it! ...what shoud i do? I already have feelings for him...
