AITA for getting mad at my fiancé for going to a party without telling me?
Today My Fiancé asked me how id feel if he went to parties to sell his product and that hed be taking me with him to the parties to sell them (Keep in mind in our past hes cheated on me a lot and the last time he went to a party by him self he cheated so we came up with a boundary of no parties unless we go together). But he tells me hes going to meet with the promoters today just to talk about it and thats it. hes there from 7:30 its now 10 i ask “is the party going on rn bc u been there for some hours now…” he said “NO” we are just outside talking, fast forward i find our from his brothers girlfriend that it was a party. hes saying “well its a lick back which is for close friends so not a party” but he doesnt know any of them there, his shirt is unzipped open in the party shirt he bought specifically for a party, he lied and said no the first time, i asked him to face time me before he left to show me, he leaves me on read, and then text 2 mins later and says “im leaving now” He gets back and i tell him to screen share and thats whenni seen his outfit, and a vide of him vibing and dancing to music and a picture in a room that was full of people and girls like a party would be WHICH is not him just “outaide talking” now hes calling me embarsssing and telling me im crazy and tripping and that its not that serious. AITA? Keep in mind he only told me it was a kick back because i found out through his brother’s girlfriend. I will add, he cheated a lor from 13 up to 17, and i forgave one more time because i thought we were super young but we are now 19 so i was thinking maybe hes matured because we are grown now
