I'm new here and pretty lonely on my fitness/ weightless journey

Hello! My stats be atm 5ft 7 and 74kg looking to get to about 60kg :)
I'm doing well with tracking my calories and starting to be more active. I have an active job so it's hard to motivate my self during the week but I'm trying my best.
My main problem is I'm pretty lonely on this journey I live my partner and he doesn't want to eat healthy at all. So my house is full of his snacks and treats like pizzas savoury pastries and crisps and stuff that's all he eat because doesn't like the healthy stuff I eat. I cant really talk to him much about health because he doesn't really listen. Like asks for advice for himself but ignores me. So it's hard to stay motivated sometimes when he's getting take out every couple of days.
I just dont have anyone to share the little victories with or little accomplishments and stuff ! It gets me down sometimes and makes me just want to give up. But I have ti make these lifestyle changes as my medications have some side effects with heightened cholesterol and stuff like that so I can't really just be eating out if moderation anymore.
I'm very all or nothing and will probably be very all in until I'm closer to my goal. That's when I need to start introducing those treats but in moderation and enjoying them in a healthy way :)

Hit me up ill keep you accountable you keeo me accountable well share our victories and just give each other good vibes :)
