I felt so bad because I saw him being hurt. I wanted to apology but didn't know how, because he won't talk to me, or he didn't want to see me. So, I left him alone, after I saw him sitting alone on the couch, I didn't want to bother him, he wanted to be left alone, so I left him alone.
When I saw him calm and he got over it, but I felt bad because when I saw him crying, and I regret all the things that I said to him.
