She was diagnosed with depression. And we were going through a rough patch (we had been together for 4 months and she did some things to hurt me) she said her reasonings are that 'she isn't able to make me happy' and that when she feels happy it 'is fake happiness'. She is on prescribed medicine too. She has also been self harming recently (I've made her stop). We still speak regularly and she holds conversations however she never seems to interact with me first. I don't want to 'chase' her and be too clingy but I want to either be with her in the future, and if that's not an option I feel like I should help her through the depression. I don't understand why she doesn't interact with me first? Does she not want to talk to me and I'm not getting the hint or is it part of being depressed and her not reaching out? We're still sexually active with each other.

I've never had a serious relationship before as I had waited to find someone I truly wanted to be with and I don't want to lose our relationship because of this.

I'd appreciate it if anyone that was/is depressed could help me to see from her point of view. Am I not leaving her alone or should I persist to make her happy?

Tl;dr girlfriend split up with me because she was diagnosed with depression and 'she can't make me happy'. She's stopped interacting first and I feel like I'm chasing her although she still has feelings for Me. Is it part of depression to not reach out or should I stop?
