#3:. Making up excuses for why they didn’t call.
If you weren’t into it, you weren’t. That’s cool. A human being with any sort of objective outlook on dating expects that there will be those guys who flake out on a second date — either because they were just looking for sex in the first place or they weren’t interested in a second one. If you have never had this happen to you, your snatch must be made of gold and your face carved by angels. I don’t know about that life. But those of us who have know the guy will always offer an excuse that involves a) being busy at work b) having life drama c) a dead family member or d) being dead yourself.
However, you don’t have to kill anyone off to be nice about it. Just be up front that it didn’t work for you. It’s not the end of the world, and I’m sure your very alive father will appreciate not being murdered just because you’re a lying prick who can’t communicate.
#4:. Lying about wanting a relationship if they don’t.
There’s always room to figure out what you want out of your dating life — to see someone while you’re figuring out where this is going. Not every relationship is the same and your needs from each person you see might be very different. But there’s a difference between “dating grey area” and “not knowing what we are to each other” and overtly leading someone on. Are you just getting out of a relationship and need some single time to just be casual? Then it’s best not to go on a bunch of escalatingly intimate dates before you let someone know that. One of the most important things in a relationship is to be with someone who gets where you’re at right now, and you can’t do that if you’re giving them what you think they want: a boyfriend. The only way to find out what they want is to communicate — and ask.
