Did your diabetes diagnosis affect your relationships?

Hi reddit community, I was diagnosed with type 2 a month ago with strong genetics working against me. I've always tried to stay active and eat healthy, but I guess I wasn't being accountable for everything I was putting in my mouth and this is the result. Since my diagnosis I have noticed a huge change in dynamics with my partner. He is a really active guy, always has been and when I first told him I was so upset with myself and his responses haven't been supportive instead I get "I told you so" or "you've only been healthy for like a week", or if I eat healthy snacks "hows the diet going?". Just very snarky narcissistic comments that highlight how bad I already feel about myself. It has been nothing but a month full of arguments despite myself being super strict, active, and I've already lost a few kgs and seen a change in my gluclose levels. But I just don't feel seen and my little wins are not acknowledged or celebrated. Everything just feels like a tug-of-war and I don't understand why there is so much tension between us. I am actually so proud of myself for the steps and changes.

Has anyone else experienced relationship problems and significant changes since their diabetes diagnosis? Please help!
