What dating truth have you come to realize? Here are 10 dating truths you can’t ignore, from Cosmo:

1. You’ll regret that “Just wanted to make sure you got my last message” follow-up to an e-mail, text, or voicemail.
2. If you don’t feel comfortable having a conversation with a guy about sex — especially condoms — you shouldn’t be getting busy with him.
3. If a man breaks up with you out of the blue, the out-of-the-blue part is really only on your end.
4. Just as it’s best to wait to drop the L-bomb until your man does, let a guy change his Facebook status to “in a relationship” before you do.
5. No woman in a healthy long-term relationship has ever said, “Gee, I really wish I’d slept with my man sooner.”
6. Keeping a change of clothes at work in case of an emergency walk of shame isn’t optimistic behavior…it’s career-savvy.
7. When a guy repeatedly refers to his exes as “crazy,” “psycho,” or “sluts,” he will use those same words against you one day.
8. If a relationship feels like too much work after the first month, it’ll be 10 times harder a year from now.
9. A guy who rates you or other girls as a number from 1 to 10 is a loser, even if he gives you a 10. You’re a woman, not county fair livestock.
10. 10.A guy who talks about how skilled he is in the sack is like a man who brags about his money. Either way, he ain’t got it. The kind of man you want to be with knows that actions speak louder than words.
