What is the reason for the moment of disappointment in a long distance relationship?

I did what I promised, and what she promised was forgot.

After 3 years of dating, 5 months in a different place, I went to him, and his first sentence was "Let's break up" Later, I knew that he had a mistress and slept. I ......

I had a cold two nights ago, he went out to drink with friends, after he went back to the dormitory, we only chatted and didn't open **, chatted two sentences and said he drank a little too much, wanted to sleep, I said "you go to bed early, don't drink so much next time, it's not good for your health, then rest quickly" I didn't tell him about my cold, this night was very unfortunate, I had a cold, my stomach was a little uncomfortable in the middle of the night, and I didn't sleep well all night, and then the next day we chatted ** and told him about it, He replied to me, "Is it so hypocritical?" It was really uncomfortable at the time, and my heart suddenly cooled, and now that we have broken up, he still mentioned it, heh.

After half a year of long-distance relationship, he came, and a week after meeting was fine, and suddenly one day told me that I couldn't accept a long-distance relationship, and I didn't quarrel It's always been fine, and it ended in a hurry.

Talking to him with joy, he said: Don't you sleep? I yawned
