You want and try to have a big effect on your lover's path into the future -- without realizing the fact that in being together, you might actually pull them away from where they really should be going. This is inadvertent and unconscious on your part, of course; and ultimately, it could have the positive outcome of illuminating where your partner should go precisely by pointing out the directions in which they shouldn't head. In the meantime, things can't be fun or easy all the time.
You're full of advice for them, but lots of times it isn't the right advice. Giving advice might actually verge into the territory of attempting to control them. Even though you have very good intentions, you just might not understand your partner's life path. You're tempted to apply all your own experiences and feelings to their goals without stopping to think about whether they really apply. You might just be on two very different paths, with two different goals, and your experiences just can't be of help to each other, no matter how crucial they've been to your own development. If it seems as if you speak different languages, it could frustrate you both -- but it could actually have positive results. Resisting your attempts to influence their life path means that your lover is more clearly defining that path for themselves.
