Hi guys, so im [F21] and have been with my boyfriend [M22]currently for 5 years. We are doing good, happy, thinking about getting married ect, but there's one problem that I dont know how to breach with him. He has a rare genetic spinal disorder and he has started to gain a lot of weight through comfort eating. This in no way, shape or form changes how I see him or how attractive he is to me but I am worried for his health as excess weight can accelerate the progression of his unfortunately incurable spinal disease and this is my main worry as I am starting to notice signs that he is having more trouble with his back already. How to I have the conversation with him in a way that makes it sound like im not being fat phobic?
