Confused

Summer

My fiancé and I have been together for almost 4 years now. I know I love him and we are most of the time happy together. But theres something pushing us apart, I dont know what it is. The life we have isn’t what I want, I’m a stay at home mom and everyday is the very same. I sit with the kids during the day and when he gets home from work we just sit on the couch watching tv or sitting on our phones. I told him how I felt and he said that last time I felt this way and I wanted to leave, honestly part of me does but at the same time I love him so much. I need some advice ladies.... 😔😔
