My DH and I have different running styles, he's more of a sprinter and I'm slow and longer distance. We've gone together and worked out a way to run together. I plug away he sprints on by. I jog and catch up, then pass him while he's walking, then he sprints on by and on and on it goes
we appreciate the differences and admire the talents we each have.
He's faster, I can jog further, he's stronger, I'm more flexible.
Don't get me wrong we have some friendly, healthy competitions, foosball, tennis stuff like that, nothing wrong with challenging each other to do better and try harder.
I remember that feeling you're talking a about, wanting to cry, when we would go hiking, I have a harder time with hills, he starts going faster because he hates them, as I've gotten stronger and fitter I can catch him.
Keep working and be proud of what you can do and be proud of what he can do, your future husband is awesome!
Congrats on your weight loss, I know how hard it is at your height! Great job
