I met a guy about 4 weeks ago, I'll spare the details. We've been on 2 dates since then, we made plans last week to hang out today. I text him yesterday to verify the plans, he said we we're still on. We got halfway through making plans then he stopped texting me, the last text I sent him was a question that he hasn't replied to. He's been online since then but hasn't replied to, should this concern me much? He could have text me back, am I overreacting? I think it would have been common courtesy for him to at least text me back today sometime. Should I wait a little longer to hear from him? What if he texts me after 5? Is it too late to accept to hang out after 5? I'm a very reasonable & an understanding person with a lot of patience but I also know our time is very valuable & I'm a person of my word who sticks to my plans with others bc I know our time is valuable. What should I do?
