My partner has depression and they keep pushing me away. What should I do?

First, and foremost, identify if they want to change or not. If they want to change and your feelings for each other are mutual then you can do somethings for them:

1. Take them to gym
2. Read books
3. Give them confidence, love they never got when they needed it
4. Say that, you will work through things together.
5. Push them to be their own biggest friend not their biggest enemy.
6. Make meaningful conversation, try to understand them.
7. Don’t be forceful or angry when they don’t do things do the things the way, you wanted.

I believe its important for you to take these steps and I also believe they will help.

but I also believe that one who doesn’t want to be helped, will never accept to be helped.

Remember, you can take a horse to a pond, but you can’t force them drink the water from pond
