Okay long post FYI…

So my husband and I have been married for almost 6 years together for about 9 total. We have a 4 and 3 yr old and life is hard. Our kids are crazy, I’m a stay at home mom, he works a lot, and I just feel like we are 1000% roommates at this point. I have talked and talked to him and I’m getting nothing. He doesn’t want to separate but also doesn’t put in any work to date again. I fantasize about living single with just my kids. Like it sounds so good to me! Butttt, I also don’t know if it’s one of those things where life is just hard right now, it will get better. Or the grass isn’t always greener on the other side. Other than the fact that we aren’t intimate hardly, and we bicker a lot.. there is no true like defining moment in our marriage that calls for a separation. He’s an amazing dad, good husband. I just feel so with drawn from him. I feel like if I had to be single tomorrow I would be okay with it. I need some stories of your marriage if it compares, or something similar. Did you stay and put in the work? Did you separate and life was good? Or a mistake. I love him I do, but I also feel like something just isn’t right. There is absolutely no infidelity happening as well so please don’t go there ha… just looking for some friendly advice. Did therapy help?
