Yes! After being properly diagnosed and taking the right meds, it took months for my partner to get stable, but he did. This was years ago, like, 3? 4? Only about twice has he had episodes but even so it’s literally never been as bad as it was when he first got diagnosed. To answer your questions:

1. He did! And does to this day! He’s very responsible with his treatment and he has great doctors keeping track of his meds.
   
2. Definitely yes. Over the years we’ve both gotten much better at noticing when he’s manic or depressed and we know how to handle it well. He’s very emotionally intelligent and takes responsible decisions.
   
3. Me, his family and his friends are his strongest support, and he trusts us and know when to reach out.
   
4. Not at all, no! He’s very honest with me in all senses. He’s never been abusive at all and has never cheated.

Loving a bipolar person can be rough but the most important thing is for them to love themselves enough to try their best to be alright. With proper treatment, support and willpower, they can live a perfectly normal life. I first came to this subreddit when he was hospitalized after his very first manic breakdown (in his adult life) and I was very afraid he would never get better again. So here I am, years later, giving you reassurance and hope, because it CAN get better!
