Went on a date Friday. Was supposed to go again Sunday and Monday. He didn't text me until I did today. It's Monday. We were supposed to go out yesterday and today. me: "how are you? :)" him: "I am doing good" 30 minutes later, "how about yourself?" me: "good" because for those 30 minutes, I felt like shit. Have I done something wrong? I fee bad. He was so nice before the first date.
I don't think you should waste anymore time with him. He doesn't seem interested at all. You being a lady and continuously texting him, may make you come across as desperate. If you were already in a relationship with him, certainly, its OK to text/call to check up on him. Not after one date. You haven't given us the details of the date, So its hard for me to say if there's something wrong you did.
You shouldn't have answered like that. You just came across as angry, not interested and have placed negative vibes all over. Dating needs to be chilled. For all you know he could have veen busy or distracted. It's too soon to be getting angry over things like this.
