I am 27 and have been single literally my entire life. I've dated, but never been in a committed relationship. Today, a guy I've gone on a few dates with was supposed to come over and have a pool day with me. I invited him out on the 4th and he told me it would be easier to reschedule for Saturday (today). So this was all his idea. However, I had a feeling that since I hadn't heard from him since Wednesday morning, that it just wasn't going to happen. I know it would have made sense for me to text him, but I felt like I was the one who was always reaching out to him first. He literally did not send me one message between the response he sent to my message on Wednesday, and today when he laughed and said, oh I have a bad memory, I didn't realize we were supposed to hangout today.

I just feel like if somebody is legitimately interested in someone, they would want to talk to them. They would want to see how they're doing at some point during the day. Why should I always be the one to reach out if he was legitimately interested in me? I shouldn't have to remind you that YOU chose to reschedule on a day that would be easier for you.

Things like this cause me to lose interest very quickly. Am I being unrealistic because I've been single for too long, or does this make sense to be irritated?
