Whether you're newly married, you've been married for 20 years or you're in a long-term relationship, you know it's not always rainbows and sunshine when you love someone. Sharing a life with another human is wonderful, but some days are harder than others ... and sometimes, those hard days can even turn into weeks or months.

Knowing what to do when those hard times hit can have such a huge impact on our overall happiness and marital satisfaction. When marriage gets hard and you don't know what to say, here are a few ideas:

1. How can I make your day better today?

When you can't figure out how your sweetheart needs to feel loved, it's perfectly fine to ask. They might be surprised at first, but you'll find that serving your spouse how they want to be served will bring you both immense joy and love.

2. I care about you

When times are rough, it's easy to think your spouse doesn't care about your needs or feelings. Banish those doubts by letting them know how much you care about them and value their presence in your life. Everyone wants to feel cared for, and your sweetheart is no exception.

3. We will get through this

There will be some days when you feel like the whole world is crashing down on you two and there's no way things could get better. But hold your head up; there are always brighter times ahead. Let your spouse know you'll stay by their side until those happy times come again.

4. "Remember that time when ... "

It's always fun to reminisce on funny memories and great times. Recall those memories and use them as a reminder that your marriage was awesome, and you'll get there again.

5. Can I do something for you?

This is especially important if your sweetheart is super busy and overwhelmed. Let them know you're there for them and are willing to help out with whatever they need - even if it's a foot rub at the end of a long day.

6. I'm sorry

Your hearts can't start healing until you apologize to each other. Saying those two simple but heartfelt words can change your situation drastically. Soon, you'll be on your way to a happier marriage.

7. I really need you

It's so important that your spouse feels needed and wanted. As much as you hate to admit it, your spouse is the one person you truly do need during hard times. Remember, your sweetheart is your best friend, and best friends need each other through everything.

8. I'm proud of you

No matter how much your spouse is driving you crazy, let them know you notice their accomplishments and efforts. Be proud of them for even the smallest things, and see your marriage improve.

9. I want to work this out

Your spouse needs to know you're going to stick through whatever trial marriage is throwing at you. When both sides of the relationship genuinely want to improve, you make huge steps toward your happiest life together.

10. I love you

Nothing is more comforting than these three words during a hard time. Even if your marriage feels like it's falling apart, that love you share will carry you on your road to marital bliss.

Marriage problems are never fun, but you can get through whatever is troubling your relationship. Try saying these 10 things, and watch your marriage turn back into something magical.
