Male, 28 years old; Female, 28 years old; relationship

I've been in a relationship with my partner for about three years. I've consistently talked to her about my mental health, but I feel like she's not really supporting me. Whenever I bring it up, she interprets it as me "bashing" her and insists that she's "trying so hard." I keep stating that all I need from her is a simple question about how I'm doing. Before Christmas, we had an argument about this. I bought a gift for her mother, and she kept asking when I would deliver it. When I inquired if she had gotten anything for my mom or sister, she replied that she "hadn't gotten around to it but would" and then mentioned how much she had spent on her own "loved ones" but would still do something. It's not about the cost or the gift for me; I value the thought behind it. Now I'm left wondering if this is a sign of manipulation or just a lack of care.
