So you know the house could never be fully clean, anyways he tells me im always in pjs and i told him your really never here to know if i am or im not yes he sees me in pjs, because he leaves at 5am and sees me in pjs because he comes home at 12 or 1am so i dont get it, than he starts talking about my weight and that has been a super sensitive subject for me, he says that i let myself go yes im a little heavier than when we met but i had 2 kids my body will never be the same and yes ive started to work out eat healthy but he dosent know for the same reason he never comunicates with me and we never really get to talk, he wasnts me to lose the weight like super quick i just need some advice on what i should do or how i should handel it, (sorry for the long story) (there might be spelling errors and im sorry for that too) help please
