Did i do something wrong?

So me& my fiance shares an IG. Yesterday I put "Soon ill be stealing my #1 bestfriend last name" he texted me "Whos your #2 bestfriend , what theres someone else" i kept telling him thats not what i meant. His mom was talking to me about outting him before everything including my parents hes gonna be my number 1 priority. He called me adumb cheating slut. I kept tryanna think words to explain to him what i meant. He called me sketchy. It frustrates me on how am i sketchy? Last week we didnt even go do our license for marriage he dug out on me to work we kept moving dates & if i fight over it im a selfish bitch. & he wants to get a TRUCK before we get married. I MEAN everything is before me !!!! I feel like im being used ! Like the same day we was suppose do our marriage license we went to the beach & he was watching a girl dress infront of him on the beach & he was drooling. Then sunday he was swearing at me cause i left the water on before we went to church we was aruging. He said "Dumb cunt cannot hear the water stupid bitch?" i told him "You know im slightly deaf you know i cannot hear very well" then he push me & told me stfu & hurry up. Now today we fighting bout him being my #1? Did i really do something sketchy? I mean i hate it when he thinks like this. Idk what im doing wrong im trying to work shit out. Im the one trying to make plans if we are gonna get married but idk i guess im sketchy right? Im sketchy by doing wifey shit for him since day A1. IM sketchy when i try talking to him about what we going do but all he does is roll a fucking joint. Tired of fighting cause i seem sketchy when he aint got time for me even when he has days off. When we go to his moms ill hide to see if he notice im gone in his mom room & he does not notice. Seems like he dont give a fuck bout me.
