I feel like I'm in a loveless marriage

To me intimacy is very important. I want to feel like a wife and not a mother 24/7. I try and flirt with my husband and don't get any flirting back. I try to initiate sex and get reject all the time. I try and wear clothing that is appealing to my husband, I work out and try to gain weight in those fixated areas. I say, show, and do everything for him to where he doesn't lift a finger. I do all the housework, I'm both mother and father to the kids, I initiate outings, I Carter to his every demand. I let him play his video games 10+ hours a day and let him sleep all day. In the past I felt more desired more connected more intimate more love from him. However, just these past 8 months I've just felt coldness from him. Our sex life is barely there and I have a high drive and try to make it a point to at least schedule it weekly with him so he also get pleased and I offer and try initiate blowjobs even and I honestly love satisfying my husband I just wish he feel the same towards me...or cared enough to see how much that sexual connection makes me feel. Without it I feel like he's distant and would rather masterbate...than get head from me or have a quickie or make love. Can anyone help a lady out? And yes I am attractive I'd say an honest 5 lol I'm average.
