1. When He Abuses You
If a man hits you or pushes you, get out of the relationship. It doesn't matter if he loves you. It doesn't matter if he promises to never hurt you again. Hurting you once is one time too many. You can't remain in an abusive relationship, even when that abuse is verbal. You deserve better.
2. When He Cheats on You
Yes, there are some special couples who make their relationships last after cheating on each other. However, the majority of the time, you should dump a cheater as soon as you find out about what he did. If he did it once, he'll do it again. It doesn't matter how much you love him, because he clearly doesn't respect you enough to remain loyal.
3. When Your Love is Illegal
You can't break the law in order to date a boy. If you have a crush on a teacher who's too old for you or on a student that's too young for you, you can either wait until one of you hits the legal age, or you can forget dating him. You don't want to end up in jail over a fling.
4. When He’s Using You
If it's clear that the boy you're crazy about is only using you for sex, you need to end your arrangement with him. If he won't call you his girlfriend, but he will sleep with you whenever he's in the mood, something is wrong. Don't let him use you, no matter how strongly you feel about him. You're not a sex object.
5. When You Want Different Things from Life
Unfortunately, love isn't enough to sustain a relationship. If you two want to last, you need to have similar plans for your futures. If you want kids, but he doesn't, then one of you is going to end up disappointed. Listen to your head and leave him, so that you can find someone who wants the same things as you do.
6. When You're Hurting Someone You Care about
If hooking up with the cute boy your BFF is crushing on is going to ruin your friendship, you should probably listen to your head over your heart. After all, don't you think your friend is more important than some boy you barely know?
7. When He Makes You More Upset than Happy
Our hearts are irrational. They'll tell you that you have feelings for someone who only brings you misery. That's why you should listen to your head and dump any boy who makes you cry more than he makes you laugh. Relationships are meant to bring you happiness, not sadness.
You don't want your heart to convince you to stay in an unhealthy relationship. You need to listen to your head when you know your heart is biased.
