Communications

Ok I have sometimes have a problem when it comes to communicating with my fiance .. he gets pissed when I tell him I heard some of the things he said.. but remind u I am not perfect and do not get mad at me when I asked U repeat yourself or u ask me something and if I say that I am not interested... I did say that I do not hear him 45% of the time but u asked when I tell u u get mad I think u should never ask a question if you do not want the answer... u said be 100 I am ... I am wanting to be the best but sometimes my mind wonders off .. yep my fault but if I am not clear I ask u to repeat it and u get mad..😑 what am I suppose to do. to me it sounds like we are in this relationship for nothing.. Love him dearly but I do not know what else to do .
