Communication

I’ve been with my fiancé for three years, four in just a couple of days and I’m honestly ready to cut ties and walk away. He’s constantly lying to me and when I try to sit him down to discuss the lies he clams up and won’t talk or he just walks off. I’ve expressed to him multiple times how I feel about his lying and the other things that he does but he just simply does not care. If I text him and tell him how I feel he sends me replies like “👍” or “k” and it’s honestly got me at my end.
