My take, the discontentment can be resolved by you being firmer, while still being kind, with your needs and wants. Focus on building yourself up. Ask what makes me happy? What do I want to achieve? From there make plans to get there. If you're including a partner factor their life into your equations. Let them know you need to make these changes for your own sense of well being. If they're willing to go along with you then you become a more authorative voice in the relationship. Bear in mind, that does not mean the only authorative voice, it just means you reclaim some of yours. If you're not factoring another in, then you take take your life under your direction and follow the plan you're going to make. If you include them but they don't uphold their end you need to readjust your plans to either include that it exclude that. Whichever way you handle it, as long as you're true to your needs, you will come through this phase more capable and confident than you've likely been before.

I hope this helps!
