No matter how sweet, harmonious or supportive the rest of your relationship may seem, there will be a sense of restriction between you, as if one or both of you isn't getting what you want at an important level. As these feelings return repeatedly, frustration could build, and blame will be a natural, if unfortunate, result. You might feel as if the relationship inhibits your freedom or your happiness in some fundamental way, or it could be your partner who feels that way.
Alternatively, you could both feel as if in this relationship, you can never have quite enough money, commitment, trust or any of the other elements that make it easy to relax and just float awhile. You may feel as if your friends or your families don't support the relationship, which makes it harder to have a carefree time together. It's possible that, even if this relationship starts out with the warmest of feelings and the best of intentions, things will really cool off emotionally between you. However, if you can remember that this is a growth opportunity, a chance to work through your mutual issues of resources, trust or commitment, then as a couple you can burn through these issues and gain the rewards of a deep and intimate connection.
