Every couple fights. Some arguments are healthier than others, but it's bound to happen eventually - no matter how perfect your sweetheart is. Every once in a while, things get more heated than normal, and someone says something they don't mean. Maybe that happened today and your husband is definitely sleeping on the couch tonight.

There are some things, however, that a man should never say to the woman he loves, no matter how heated the argument might be:

1. Is it that time of the month again?

When you ask your wife if she's on her period, she knows it's really just your way of saying she's acting irrationally.

"That time of the month" doesn't affect a woman's ability to behave rationally. If she's upset with you for doing something while she's on her period, it probably still bothers her during the rest of the month.

Also, it's incredibly degrading to play "that" card in an argument. Blaming her emotions on her period means you're not trying to hear her out and you are treating her like a child. No matter how upset she is and no matter how much proof you have that your wife is on her period, don't use it against her.

2. Are you really going to eat that?

A woman doesn't need anyone else ragging on her for her dietary choices - she probably does that enough herself. When you ask her this, it makes her feel like you don't love her the way she is, or that you won't like her if she goes up a size. For the sake of your relationship, don't critique your wife's eating habits.

3. You don't need to get so emotional

Women are naturally more expressive than men. Your wife is probably already bothered that she's so much more emotional than you, so when you say this, she becomes even more self-conscious. Telling her not to get so emotional is just asking for waterworks and a big wave of more emotions.

4. You knew I was like this

You don't get to blame your wife for your character flaws. If you're feeling guilty for being a certain way, it's unfair to decide you're not going to change and blame your stubbornness on your spouse.

A relationship takes a lot of work and sacrifice to be successful, and that includes dropping bad habits for the sake of your partner.

5. You wouldn't understand

Maybe she doesn't, but you don't need to make her feel dumb. You wife most likely understands better than you can imagine. And if she really doesn't, take time to help her understand. She'll appreciate the amount of patience and trust you have in her to help make her the person you confide in.

6. Is that really what you're wearing tonight?

She spent a lot of time deciding what to wear tonight. She probably tried on seven different outfits and got all ready before changing her mind at the last minute. But even if she just threw on sweats and a tee-shirt, you don't need to make her any more self-conscious. Tell her she's beautiful and move on.

7. My mom makes it better

You don't need to give your honey yet another reason to feel like she's competing with her mother-in-law. She's made you a meal, and all you need to say is "thank you." It's even worse if she took extra time to recreate your favorite childhood meal, only to have it shot down. Nothing is ever going to taste a good as the nostalgia of childhood, so appreciate what your wife does for you and let her know how grateful you are.

8. Calm down

Women can sometimes overreact to things, but you shouldn't dismiss her feelings. If your woman is upset, instead of telling her to calm down, help her to calm down by holding her and listening to her (and pulling out that pint of Ben & Jerry's).

9. It was just a joke

Women know a good joke from a bad joke when they hear one. Just because you meant something as a joke doesn't mean it wasn't offensive. Defending yourself with this little line means you can't own up to hurting her feelings, and that's not something a woman wants in a relationship.

10. What have you been doing all day?

We get it. You work hard. You come home from a long day at work and you just want to relax. But women work just as hard - whether or not they work outside the home. When you ask them what they've been doing all day, as if they've just been sitting around doing nothing, it shows that you don't appreciate the work they do for you.

Men, instead of saying these things to your woman, tell her you love her. Let her confide in you without you putting her down for being overly emotional. She'll appreciate and love having you in her life and your marriage will be stronger for it.
