I'm contemplating

So I have to add this anonymously because my husband is also on this app.. But for quite some time now maybe the last few months I have been contemplating leaving my husband.. I have grown tired of this roommate situation... like we have sex and we do make important decisions together but otherwise it just feels like we're roommates.. he comes home from work and 80% of the time doesn't even acknowledge me.. if I text him during the daytime while he's at work he will not respond to me but let someone else text him his mother his brother his friend and he's quick to jump on a reply for them.. I can't take this feeling that I have no place in his world except for at the very bottom.. he sits on the couch and does nothing but watch TV or play this racing game on his phone.. most of the time if I try to talk to him he doesn't even seem to hear me because he's too involved on his phone or the TV.. I feel very very inadequate.. most of you ladies are probably going to tell me that I need to communicate with him let me tell you I've tried maybe not in the best of ways, because I can't seem to get the words out where they make sense and all he seems to do is just get mad or say that he will change but nothing ever changes.. 90% of the time he's cold and distant and only when he wants sex does he seem to be nice to me.. I have tried several times to tell him no to sexual advances but he seems to think it's still a game from when we were dating because he'll grab my mouth not hard enough to hurt me but he'll just put his hand on my mouth and tell me to to shut the fuck up that he knows that I want this and to quit fighting, and then he does this thing while I lay there, when he's done he tells me he loves me and goodnight but it's like he only does it because it's something that's been programmed, like I don't feel any connection anymore.. I just don't know what to do I want to get up and leave but it's so hard to throw away something that I worked so hard for. I don't understand why he can't put in any effort.. I know I'm probably just wasting my time, but I do love this man I have worked very hard at this relationship more than I have in any other relationship in my life.. before him I wouldn't put in a whole lot of effort especially if the other person wasn't...
