Think of “love” as a verb, or an action you have to continue to reinforce and support as you move forward in your relationship. Consider how your girlfriend actively contributes and cultivates her relationship with you, and if your relationship is just as good, if not better, than when you first fell in love. Through action and words, your girlfriend can reinforce and commit to the relationship every day, even in small or seemingly insignificant ways.

Successful couples who are committed to the relationship for the long term will try to work on solving any problems and letting them go. They will focus on taking care of the issue, rather than attacking each other or freezing each other out. In a healthy, loving relationship, both partners should be able to forgive and forget, as any lingering resentment that is not addressed and dealt with can lead to further drama or conflict down the line and will work against sustaining the relationship for the long term.

Opposites may attract, but they rarely make for a good long-term relationship, and compatibility in your tastes and preferences, as well as your values, priorities, and life goals, will help to create a deep and lasting connection between you and your girlfriend.

List the four dimensions in a vertical line. Write Partner A and Partner B on top of the list of dimensions. Next to each dimension, rank whether it is a “Must” have, a “Should” have, or a “Could” have for your relationship. Pass the list to your partner, and have them rank the dimensions. Or, mark down how you think your partner would prioritize these dimensions. The more “must-must” and “must-should” combinations between you and your partner, the greater the possibility of an intimate and long term relationship. Since no relationship is static, especially a healthy, loving one, the rankings of each dimension may evolve to be even more compatible over time. Understanding each other’s priorities, especially in these core areas, will help to ensure long term success in a relationship and staying in love.

Though it’s important to trust your own instincts and feelings, it’s usually a positive sign if your friends and family support your relationship with your girlfriend and think you have long term potential together.

Love triggers the release of serotonin in your brain, and it is believed that high levels of serotonin can cause you to think constantly about a partner. So the more your partner calls you or talks to you, the more they are thinking about you, which is a (chemical) indication of their feelings of love for you. [7] X Research source

If your partner truly cares about you, they should be willing to hear your opinions and ideas, and engage in a civil, respectful discussion about subjects you may not agree on. She should also be comfortable with including you in decisions, from mundane things like where you should eat dinner to high-stake questions like whether she should accept a new position at work. Though she may not always take your advice, she should still be interested in hearing what you have to say and take it into consideration.

This kind of trust shows true caring, and is a big sign of a long term commitment.

This doesn’t mean your relationship will always be a bed of roses, but overall, you should feel like your girlfriend gives you self-confidence and support, rather than negative thoughts or low self-esteem. If you are with someone who makes you feel good, you will not only want to spend more time with them, but also regard yourself more positively during the times that you are apart from them.

This will also put you both at easy and make you both more comfortable with talking honestly and openly.

If you feel strongly about her, indicate this to her so that she feels comfortable enough to share how she feels about you.
