<human>: Can you succinctly summarize the text in 1-3 sentences?

When we met I wasn't a smaller girl, about 170cm and sitting around 70kg. So curvy, but not fat. Anyway we fell pregnant and I put on a shit ton of weight, 40kg to be exact  and it was all my doing. After having our daughter I became severely depressed because he was always drinking, physically abusing me and saying absolutely horrible things about my weight. One example is that he used to mock me by puffing up his cheeks and shouting 'boom boom boom' as he took steps towards me. It was absolutely horrible and I was in too dark of a place to get myself out of the relationship which was now toxic. He woke up to himself, quit drinking and again became the lovely person that I once met. I was seeing a psychologist and was prescribed antidepressants which helped me out of depression. I changed my lifestyle and lost 25kg. In the past few months I've had a hard time, I have lost 2 babies- one to miscarriage and another to ectopic pregnancy, which I was in hospital for. I stopped exercising and slacked off a bit with my diet, I've only put on 2kg in about 4 months but I'm now pretty much back on track diet-wise. Since I've slacked off however, my SO has been making rude remarks about my weight again, then apologising afterwards. It hurts me a lot but I forgive him every time. Tonight he called me fat, apologised, then immediately made more hurtful remarks about my weight. Now he's grovelling and apologising profusely but I'm sick of it and I don't want to just let it slide again this time. What the fuck should I do!?
<bot>: SO caused me to spiral into depression by tormenting me about pregnancy weight gain. After losing 25kg he's doing it again and I don't know what to do.
