My boyfriend is 'supporting my decision' regarding losing weight.

I'm not sure if this is a good thing or a bad thing, nor am I sure if he knows the extent of my decisions.
When we first started dating he used to tell me how sexy he thought my jaw line was (Kind of random but I liked the compliment) and since the relationship started almost 2 years ago I had gained weight.. Since then I haven't heard a thing about my jaw.. I'm pretty sure it's because it's now hidden in a ball of fat and I want to cry so hard when I think about it.

I also wish my family didn't keep junk food in the house because I wound up eating a hot dog with cheese and duritos, then later I ate a bowl of ice cream.. What the fuck is wrong with me?! Every time I see some progress I manage to throw it out of the window because something ALWAYS has to come up.. Thankfully though I'll be house sitting from the 18th to the 21st for my aunt and uncle and they don't really have junk food in their house other than soda (which I will have to punch myself in the face just to stay away from) but at least they have multiple exercise machines (unlike this fucking house). I wish I had more chances to use equipment. I have no money for a gym membership and whenever I'm at Lucas's house I can't use the treadmill because it's shacked up in his mom's room and I feel too awkward to use it while she's in there. It's just weird to me and I'd rather not.

And I know I keep talking about this but I'm so fucking annoyed that she has so many opportunities to make herself healthier but she never takes advantage of them. I don't want to be like that. I want to me thin and beautiful. I want my thighs to be thin and I don't ever want them to touch. I want to have a flat stomach. I want to be a person that Lucas can be proud of. I want him to show me off but first I need to be worth showing off..

I just want to be beautiful.. I don't want to keep crying over this.
I'm now using a stop watch with everything I do and cleaning my room I only burned 111 calories.. Which pretty much just burns off the hot dog bun(110).. I still have to burn off the doritos (About 280kcal), the hot dog (120), the cheese on the hot dog (Unsure) and the bowl of ice cream I ate (Probably around 250kcal if not more), and the two rice cakes I had when I got home today (70).

I'm such a fucking failure.
Food log break down: 
110 + 280 + 250 + 70 + 50(taking a guess for the cheese, shredded, not a lot)
= 750 - 111(cleaning) - 26(jogging in place) = 623

AT LEAST I MANAGED TO STAY UNDER 1000kcal SO THERE'S THAT ♡♡♡

12:22am EDIT:: 
623 - 195(treadmill) = 428 - 446 (heavy cleaning) = -18 + 156 = 138 net intake

Now that is how you turn your bad calorie day around.
