Congrats on the weight loss since you did it for yourself and not for some jerk who is shallow and superficial. Let’s say you do get with him. Heaven forbid you gain weight after birthing his offspring or you get into an accident that disfigures your body. I don’t think it’s worth it. Find someone who loves you also on the inside. Looks can only last for so long. We all grow old, gain a little weight and grow grey hairs eventually as we age. It’s what’s on the inside that counts.

Tell him to go away. Someone who loves you before the change is someone worth keeping ..

cant be upset with a preference. we all have them, i understand loving someone for who they are but there must also be a physical attraction. that being said, i dont think you're wrong in your assumption

Setting aside any personal opinions about such a requirement, yes, it does sound like maintaining a certain weight is a condition, for him. Ask him if you're not sure, and be honest about whether or not you intend to. Be honest with yourselves and each other. If he's shallow, it's something you know and accept going into the relationship.

Tell him you can't date him since you only lost 85lbs then go find someone who wants you for you, not your number.
