You've been together a while now and it already feels different from past relationships. There's something different ... something better about the time you're with him. It's the butterflies you get in your stomach every time you see him, how he treats you better than anyone else, and how after all the time he still manages to surprise you.

If you feel like you're in the best relationship of your life, chances are, you are. But if you still need convincing, here's five signs it's true.

1. You're comfortable together

There's that old saying, "Home is where the heart is." It couldn't be more true when you're together. You know you've reached the peak of comfort when you can come home and relax with your man without worrying about the world. Home is anywhere you're with him. And there isn't anywhere else you'd rather be.

2. You can have open conversations

At this point, there's very little you don't know about each other. You can have conversations with each other about everything. But the more open your conversations are, the more you learn about each other and the more you fall in love. You practically know the inner-workings of his mind, and probably are the only person in the world who knows him as well as you do. And that makes you feel like the most special girl in the world.

3. It's easier to be yourself

There's nothing you need to hide from him. He doesn't judge you for your little quirks (in fact he loves you all the more for them). He loves everything about you, even the things you don't like much about yourself. But that what makes loving him great is the fact that you can be yourself whenever you're with him and he can be himself with you. You fit together perfectly and your love only grows stronger because of it.

4. You lean on and support each other

Things get tough sometimes. When the unexpected happens and your love for each other is tested, rather than pushing each other away, you pull each other closer. There's no one you'd rather have by your side to help fight your battles than him. He lifts you up, helps you to see the positive in life and you do the same for him. Together, you know you can accomplish and get through the very worst parts of your life. Once you know that, you know you can conquer all of life together.

5. You accept each other's imperfections

No matter how much you'd like to think you're perfect, you're not. And neither is he. Knowing that each person has a weakness (including the love of your life) is the first step to accepting each other fully. If you can love someone for his imperfections and he can love you for yours, there's practically nothing stopping you from making a future with him.

If you can say yes to these five signs, you're probably in the best relationship of your life. Make this one last because it sounds like you've hit the jackpot when it comes to relationships.
