Compulsive liar

So I may sound like an ass but this is where I’m at right now. I have been married for almost 3 years now and I do not like my husband anymore. I’m not emotionally or physically attracted to him anymore. I do not want him to touch me and when he does, I get disgusted. The thought of sex with him makes my skin crawl. I don’t know what the hell happened. 2 months after we got married I found messages from him and his co worker sexting but I feel like I’ve gotten over that. Because I genuinely don’t care anymore. He is so cocky and thinks he knows the answer to everything when really, he’s just pulling stuff out of his ass. When people notice something that isn’t true, they’ll point it out and he will say “oh well I guess that’s just not the way it is here.” He can’t be wrong. And he will just flat out lie to make it seem like he knows things. For example: he will say things like “yeah we took our dog there the other day and he loved it” when in reality.. we never went. I know it doesn’t seem major but it’s every single time we are around people. He’s just so used to lying. I don’t want him around my family anymore because he embarrasses me because I’m pretty sure they know he’s just bullshitting all the time. I feel like I don’t know this person. I used to think he was so smart but now I know he just makes stuff up. I’ve stopped asking questions and just research things for myself because I KNOW 100% that I’ll just get a lying answer if I ask him anything. I don’t know what to do. I’m just going through the motions of life at this point. Has anyone else been through this?
