I've heard this before but had an experience that I think is important to share. I had a lot of things on my to do list, the gym etc. I got most of them done and went out with a girl, the next day I didn't have anything left to do so I became fixated on girls. The fact that I wasn't getting quick replies by text made me sad and not going to the gym for an unrelated reason made it even worse. Have things that you're continuing to work towards guys. Yes talking to multiple girls helps, but if that's all you're doing you need to find another purpose.
