Can your lover give you the space you need to move in the direction that's right for you? That is up to them, and up to the other aspects influencing your relationship. It is an important issue that comes up again and again, because your lover's vision of success and your life path just don't match up.
You have two choices in how to deal with this: You can either struggle against each other and waste time trying to force, manipulate or charm your lover into doing things your way, ignoring their career and their dreams to tag along as audience to yours; or you can each take a step back and do your own thing, and let your partner do theirs. This could be really hard, though, especially if your partner's career takes off before yours does. They might start needing to travel a lot or be out in the public eye, and you could feel left behind, alone and neglected. The truth is, it is equally hard when you're both finding your success and moving forward into your futures, especially if you've fallen in love with each other -- because it might be very difficult to find time to just get together, relax, enjoy each other's company and nurture the relationship. So what's most important to you -- the relationship or the career? Make the choice, and then set that as your first priority -- and make the other a close second.
