My boyfriend [M20] and I [F20] (145lb) both believe that I'd look better if I lost some weight. However, it bothers me that he wants me to lose weight... (I'm feeling uncertain about how I should react).

This is a lengthy message with a lot of context, but I really just need some advice on my boyfriend's intentions and how to approach a possible discussion about it. Am I overthinking things? I've been feeling uneasy about a situation for a while. My boyfriend believes I'd be better off at a lower weight, and surprisingly, I agree with him. For some background, we've been together for a little over a year. When we first met, I weighed around 155 lbs at 5 feet 7 inches tall. I’ve always been quite strong, engaging in various sports like volleyball and swimming, and even excelling in long-distance running. Despite being fit, I've had an ongoing struggle with binge eating and an unhealthy relationship with food, which has complicated my desire to lose weight. In the year leading up to our relationship, I managed to drop from 165-170 lbs to 155 lbs. Throughout our time together, we've discussed personal goals, including my aspirations to drop to around 130 lbs for both aesthetic and health reasons, and he's been supportive of this. However, earlier in our relationship, when I mentioned my weight loss efforts, I stalled and ended up back at 155 lbs. During this time, I shared my past weight struggles with him, including my peak weight of 170 lbs. His response was that he wouldn’t have approached me at that weight, indicating that I was "at the limit" of what he found attractive, raising fears of being beyond what he deemed acceptable. He then added that my current weight was still close to his limit but that his love for me made me more attractive. This revelation hit me hard, and we talked about it afterward, where I think he started to understand my perspective. Fast forward to now, I've lost weight and am currently at 143 lbs. I've also gained strength at the gym, and he's been encouraging throughout this process, which has helped keep me on track. I feel great, have visible muscle definition, and my friends have complimented my progress. My goal is to reach around 130-135 lbs, but I'll stop if I begin to lose strength or have health concerns. However, he can be a bit overbearing regarding my diet—asking about my weight or if I’ve had a “bad food day.” While I appreciate the motivation, it can feel excessive, especially given some insensitivity in his comments since our earlier conversation. We’ve discussed our ideal body types, and I expressed that I appreciate a fit look. When he shared his weight preference for me, stating a range of 120-160 lbs, it left me feeling disheartened since I had recently been at 160 lbs and was fit then. He has reassured me that he finds me attractive as I am now, and he wants me to be healthy for a long life together. I'm just feeling very confused. While I love him and appreciate the results of my weight loss journey—something I've wanted for a long time—I can't shake the feeling that if he struggles to see me as attractive at 30 lbs heavier, does he truly deserve me when I’m a visually fit 10-15 lbs lighter? Is this shared desire to lose weight a negative aspect of our relationship, or is it something we can navigate together? I'm looking for outside perspectives on how to approach this situation. What should I say or do given the context?
