Taking risks in relationships is a good thing for the following three reasons:

1. Means extending trust.
If you take a risk in a relationship it means that you are extending your trust to the person. If you do not have trust, a relationship won't survive. Risking your heart, speaking from the heart, and putting yourself in a position where you could get hurt is not always the most appealing thing, but it shows trust. If you always play it safe, you can safely say that you will always be alone. The more you give in a relationship, the more you can take. So, don't forget, without risks, trust can't exist, and without trust, a relationship is doomed for failure.

2. Means learning with each relationship.
When you take risks, they do not always pay off the way you want them to, Maybe you break up, maybe you get taken advantage of, maybe your heart gets broken and your feelings trampled. However, all risks pay off. Some pay off in the currency of knowledge. These kinds of lessons can be hard to learn, but they help you in the long run. You learn about yourself, you learn about the dynamics of interaction with people, you learn about what you are willing to risk, and what you aren't. You also learn that the person is wrong or right for you, and why. So, take risks to learn more, and set yourself up for future success.

3. Without risk you don't get great reward.
The idea that you can't know evil if you don't know good, that you can't know sadness until you know happiness, etc. holds true for relationships. You can't have the rewarding, fulfilling, long lasting, eternal, meant to be relationships without taking a few risks. It is scary, and sometimes you come up short and get hurt, but if you don't take them, you never allow yourself the possibility of potential of having a really great relationship. You will always find things to be superficial and "fun" but without substance. The best relationships are the ones where you put yourself out there, and risk letting someone hurt you because you have let yourself be vulnerable.

Risk taking in relationships does not mean letting someone treat you badly, or putting up with things you shouldn't, it means extending your heart even if you know there is the potential to be let down, etc. It means letting the walls down, and seeing what happens. It means putting faith out there.
