<human>: I spent about a year before going back to college mentally and physically preparing myself for the adventure. I ended up losing 110lbs but gained 50lbs back when I ended up hurting myself and then not watching what I eat or doing cardio. I'm now healed and looking to lose the rest of the weight I need to but my girlfriend of 1 year seems unwilling to buckle down for anything more than physically working out. 

My girlfriend will go to the gym with me and will workout and push herself that way she seems completely unable to commit herself to eating a strict meal plan and making sure it's healthy. The fact she's unable to do this, though I've explained multiple my feelings on this and that this is something we need to do, makes it hard for me to eat healthier when she suggests ice cream, buys candy, or orders food. 

Also the fact that she refuses to eat the same food more than once in a day is driving me nuts. I love her but I don't know what to do to make her understand and I don't know if I can keep dating her if she's unwilling to fully commit to this.

Can you condense the text into three sentences or less?
<bot>: My girlfriend is unwilling to commit to the nutritional related side of weight loss with me and it's hurting her weight loss and mine.
