Me 30M don’t have any feeling towards my wife 29F

We have two daughters(4years)(10months) and I am not happy. I don't feel anything towards my wife, when she hugs me I hope this hug ends as soon as possible. I live in Canada (I don't have any relatives here) and she also doesn't have any relatives here. I can't tell her that I don’t like her for fear of breaking her heart and for the sake of our kids but I feel like we'll end up divorced just a matter of time. I think the main reason for this is in the sexual relationship and the coldness between us. I don't know how to describe it. She cares a lot about money and I don’t. She has some fat in her body, and I hate it so much, I told her may times to do some workout I bought her machines to do workout but she did not listen to me. I need some space alone to think about it. So I am leaving the country for few weeks soon is that good or bad idea? What should I do? My financial condition is not bad(I own a House and my business). Does anyone have a similar experience? What stopping me from divorce now? Is the kids and cz she s alone here I don’t wanna give her hard time. Any advices will be appreciated (dm open as well)

Note: I m not good in writing and explain things so I am open to questions)
