Before I start I should state that I am NOT fat shaming. Have name changed for this as I don't want to be outed in rl as this would humiliate DH.
My DH was very slim when we first got together. However over the past few years he's been putting on weight at an alarming rate. I still think he is incedibly handsome and I love him just as much as I always have but I'm very worried about his health. I have no idea how much weight he's actually gained but it's approx 4 stone in under 3 years.
I know this can't be good for him and I don't want to lose him, but he can be quite sensitive about things like this and I don't want to hurt him. I just want us to have a long healthy life together.
I've tried suggesting a healthier diet and more exercise numerous times. He agrees at the time and sticks to it for a couple of days but he will be back on the sugary snacks by the end of the week.
How do I tell him he needs to lose weight without being hurtful? Also, how do I convince him to stick to it?
