<human>: Can you provide a brief overview of the text?

My wife tells me sometimes that she feels like I'm not supportive of her, and that she doesn't feel like I do enough to make her feel safe and loved. I've asked her what that looks like for her and to give example of ways that I've been unsupportive, and ways that I could potentially be supportive, but she side-steps the question. I'm not sure if that's because she doesn't know, or if she thinks I'm stupid and should figure it out on my own. Either way, I'm trying very hard to figure out what she needs from me, and I could really use some advice in that area. I love her to pieces and she means the world to me, so it's not that I'm not feeling it, I'm just not expressing it to her satisfaction, and I'd like to fix that.   

I thought about what I might like from a partner if I was in need of support and I wanted to feel safe and loved, but it doesn't seem like any of the things that would help me are applicable to her. Where should I start? My first instinct was to think supportive = financially supportive, but that's something she's been very clear about NOT wanting or needing. We make comparable salaries and share expenses, and she has been adamant that that's exactly how she wants things to be. She dislikes it when I spend money "frivolously" on gifts and things for her, and she doesn't want me to be the sole breadwinner.  

For context, we are both very busy. We both work full time, we have a kid and two dogs, and she is also in school part time. So I know she feels stretched very thin a lot of the time.
<bot>: What does "supportive" look like and how do I do it? General suggestions would be great, but specific would be even better if possible.
