“I just can’t get over the depression her father puts me in.”

It might be more helpful to rephrase that statement as your partner can’t “put” you into a depression as it’s your experience of your partner might.
It might sounds like semantics however the difference is important.

(You might be surprised at how the way we say things and the words we use matter!
You might not have meant to imply that your partner put you into depression but some part of you did, perhaps subconscious part, and doing so made you a victim and left you stuck.

If your depression is always something put on you then the only way out of it is also out of your hands. Your partner must change.

By recognising that it is your experience that has resulted in feeing depressed you take control. You will still feel depressed but now you are in a better position to do something about it.

By identifying what it is within the experience with your partner that is bothering you, being specific about it, you will be more able to make the changes you need to.
