Whether you're single, dating, or in a relationship, there are signs you definitely should not ignore. What you decide to do about them, is still up to you of course #wakeupplease, but acknowledging some will hopefully help you avoid wasting your time.
1) They're not sure about what they're looking for. Give me a break. Why are you on a DATE if you're looking to stay single?!
2) They just got out of a relationship. If it's really recent, stay away.
3) They've dated a friend. First, girl/guy code is a real thing. Second, don't you already know a bit too much shit about them? Third, really? is there no one else?
4) The bar/club is their second home. Wild guess: they are not looking for something serious.
5) On their cell all the time. Chances are they're obsessed with themselves and their number of followers.
6) Workaholic. Get ready for the "I'm too busy" excuse.
7) Lifestyle opposites. You're a gym freak and they have a completely different definition of a "6-pack". I would just say don't catch feelings too fast.
8) They always cancel last minute. Clearly they playin'
9) They live far away. Long distance never works and I will definitely write a whole post about that.
10) They suck in bed. It's not gonna change. Your preferences most likely do not match at all, and you can read more about that here.
