The first love of my life had severe depression. It was heartbreaking and awful. After we ended after 2 years (not directly due to the depression), I told myself that as much as I loved her, I would never allow myself to get in a relationship with someone like that again. It's too much.

The second love of my life had issues like anyone else, but the depression and anxiety didn't REALLY manifest themselves until a year into our marriage, after we were together for 6. I wanted to run. I wanted to quit. Not from the depression alone but because she refused to acknowledge a problem until it got REALLY bad. But she promised she would work on it, she promised we'd talk to a counsellor. I stayed. She went on anti-depressants. We talked to a counsellor. We got through it. Things got good again.

But they'll never be 100%. In the year since then, there have been 2 more dips. Each time, like the last, she refused to acknowledge a problem, I faced the decision "Well, either the person I love is a terrible person who I don't want to be with, or they're suffering from something, and I need to be there to help them." Each time she finally admitted a problem, and things got better. But she doesn't want to talk to a counsellor anymore. She's too stubborn, too independent, doesn't want to admit weakness. (Not because I would judge - I'm much more the empathetic and emotionally open of the two of us). So I don't expect us to be ever 100% again.

All this to say that I would give the exact same advice as you, thro32. If you still have the choice early, get out while you can.
