Congrats on both your losses.
My bf is doing slimming world with me and although he is losing a lot more than me a lot quicker, he is really supportive and helpful. My bf claims to not like veg but I have managed to get him to eat a few things he didn't before; mushrooms, broccoli, even carrots if they are cleverly disguised.
In fact one of my broccoli dishes is now his favourite when at first he claimed to hate broccoli.
He used to be really sporty but gained weight cos he can't play anymore but he is now running and swimming, he is much more partial to exercise than me, hence why he is losing weight more quickly plus the fact that he is stricter on the plan and the usual fact that he just has more to lose. If I had lost weight at the same rate as him I would be at target by now.
