Your date might be more subdued when it comes to PDA, and probably won't talk about their Brady Bunch memorabilia collection as much, but they still should make an effort to show you they care. If they prioritize impressing their friends and leave you wondering what stranger you're at Chili's with, you should ditch them.
You've caught them in at least one lie
Trust is an incredibly tenuous thing. It takes years and years to build, and almost no time at all to destroy. When you're at the beginning of a relationship, trust is even harder to navigate.
If you're just getting to know someone, you may be tempted to overlook a lie and cut them some slack. But early on, what the hell is there to hide? Either this person is covering up an underground fight club... or they're just a jerk.
No matter what the reason for lying is, you shouldn't put up with it.
