I don't know if this is the first or second time you've lost weight but speaking as someone who has done this twice now, I say this with kindness -
STOP!
When I was a teen, I weighed 140 up until I turned 18. By then, my weight had reached 160. By September of, oh, what was that...2007? I weighed 130. I managed to not only shed the weight I'd gained but I also managed to shed an extra ten pounds!
Well, my boyfriend kind of put a stop to that... Unintentionally but, yeah. He told me to focus less on eating and exercising and more on just enjoying life. The thing is, he's 5'10" and struggles to put weight on, he'd never understand where I'm coming from. I didn't understand this at the time and between "enjoying life" and our miserable relationship, I ballooned up to 181 pounds by September of 2011.
It's taken me until today to reach 135 pounds. I could have been thin this entire time, working out, improving, making friends, feeling confident...but I lost all that time to bad decision making.
Just think of all the time you've put into this so far and how much you'll lose if you quit. Tell your boyfriend he's enabling you and you'd like him to stop. If he can't, you'll have to do it on your own and you
can do it on your own, I promise!
