Dude, no one is giving abuse.....
With regards to your lass, you say you love her and are "in it for the long haul", but, one year into the relationship, you are finding faults with her.
Yeah, so she complains she looks fat (as most women do....sorry, girls!) and is tired - does she have a stressful job?
Are there other things bothering her, which could lead to tiredness, depression, etc?
Just because you like to exercise or cook healthy, doesnt mean everyone should - i dont, for a start.
After working eight or nine hours of the day, the last thing i want to do is go out running in the frickin cold!!
Why not sit the lass down and have a chat?
Maybe you'll get the answers you want and save from getting the "abuse" you've been inundated with on here!
