It feels like my fiance never wants to talk to me anymore we are la

I’ve been with my fiance for nearly 2 years now and he works a 6 days a week as a marketing manager. when he’s at work I like to give a little text to see how he is and whats he doing and he Just replies hardly anything or doesn’t at all, its like he doesnt have time for me when he is at work whereas before he used to text and ring me all the time to let me no im in his thoughts etc. I try talkin to him about how I feel and it ends up in a massive arguement and im left at square one nothing is solved when he comes home he is always to tired to talk doesnt wanna talk to me doesnt comment on the dinner I cook for him it just feels like he’s bored of me. I dont know if its me that I am a needy person and love affection or he really doesn’t want to talk to me. I understand he has a hard job and hes always busy but I text him when I know he’s not busy and he doesnt want 2 communicate with me on his breaks his collegues he’s with 6 days a week is more important and I never come first. I need help I dont know what to do anymore I really love him and want to be with him but he’s making it so hard for me please reply ASAP thanks jo
