1. He/She tells you things you don’t tell anyone else:
This goes beyond random talks. If there is a desire to share intimate details about your lives; this means you both trust each other, which implies a major component of successful long-term love.
2. He/She lets you see his/her weak moments:
It’s easy to be happy with someone when you’re feeling good about life. But what about when you’re not doing so well? Do you want to see her when you’ve been denied a raise, or your cat died or you had a plain old bad day? She/He should be a comfort during tough times, not a burden.
You don’t want to change the essence of who he/she is. There may be stuff that irritates you in everyday life, but you accommodate and respect what they like, eat, watch and often do.
4. He/She wants you to meet his/her parents:
You feel proud of him/her and you want to show him/her off—as opposed to feeling like you have to make excuses for him/her.
5. You can imagine a future together:
You don’t have to practice writing your first name with his last name, but do you periodically let your mind wander to picture a life together? Is it amazing? You mostly discuss about the kind of house you want or probably how many kids you would like to have, without deliberately planning to discuss it.
6. You’re not afraid to argue:
You know that even if you fight, he’ll/she’ll listen to you and won’t brush you off. He/she takes you seriously, even when he/she thinks you’re wrong.
7. You want to work out your major difference
If you do have crucial differences that will impact your future together—different opinions about religion, money or something else—you want to work them out with him, and you believe you can come to a conclusion that will satisfy both of you.
8. You laugh together:
Laughter is one of life’s simplest pleasures—you should definitely be able to crack each other up.
9. Incredibly attracted to each other:
Physical chemistry is an undeniably important ingredient in a healthy relationship. And if she’s/he’s not a your usual “type”, that’s even more reason to think she’s/he’s the one.
10. It’s OK to be quiet around each other:
You don’t feel like you have to fill the space between you with chatter or other interaction. Instead, you feel an easy comfort.
11. You feel like yourself around each other:
You don’t feel like you have to edit your thoughts; you’re not self-conscious or anxious.
12. You long for each other:
You long for him/her—but not too much. Some neediness is good but too much breeds discontent.
13. You don’t feel too jealous:
You’re comfortable with him going out with his friends—even the opposite sex. You let each other have your own lives and hobbies.
14. You feel like she/he makes you a better person:
She/he makes you feel smart, funny, attractive, creative—like the best version of yourself. You feel like she brings out and complements the best parts of you.
15. She just gets you:
Sometimes it’s that easy. You feel like she/he understands some essential part of you that you can’t explain or articulate. It’s a warm, comfortable feeling—and one you should have with the person you marry.
16. Honest discussions on sex:
When you find yourselves honestly talking about your bodies and sexuality, then you both almost have nothing to hide from each other. Talks about sex positions, whether or not to accommodate oral sex or other forms of sex is an indication you are considering settling down.
