When you start dating someone you want to know if it will lead into a relationship. Will they become your bf or gf? Here are some red flags I've noticed in dating. Also all of these can relate to women or men.
Too busy to make plans. If they're too busy to set a second date or even a first date. That's a red flag. People make time for things they want to do. That includes dating.
They take too long to text back. In the modern dating world it's uncommon for someone to not have a smartphone. Let alone not check it every few minutes. If you get hit with the excuse "I didn't get your text" it translates to "I ignored your text."
You never go on dates. This means that you only hang out at their place or yours at night. You don't get day time hangouts, weekends or actual dates. Remember dates can be free! If they don't want to be seen in public with you during normal hours. It's not a good dating sign!
