I asked him out then he stopped responding

Hi there!
I know this situation can be really frustrating! From what I understand, you guys haven’t met in person yet? If this is the case, and he is not replying to your message, I will be blunt: if he wanted to talk to you, he would. No one is too busy to take a few minutes to reply. Something is clearly going on with him, could be work or maybe he changed his mind about seeing you. Ultimately, it sounds like he has to figure out what he wants. In the meantime, you should continue to text or talk to other men and keep your options open. If he wants to pursue you, he will text you back and agree to meet up. Otherwise, you are going to invest too much into someone who doesn’t deserve your time and energy. For now, give him time and don’t call or text. Let him come to you. If he does, you can see where things go. Don’t ask him what happened or give any indication that you were worried about what he was doing during the time he didn’t reply. Simply give off the vibe that you were so busy living your great life that you didn’t have time to care about what he was doing. This will have him questioning weather you are still interested, and he will be motivated to step up his game. But if he doesn’t, then you’ll have avoided wasting more of each other’s time. Hope that helps!
