Looking for some words of encouragement

Girls, I have a confession to make.. My husband and I have been together since high school. Our relationship has always been different. Since the beginning he has cheated on me, and a year or so later when I finally found out I confronted him about it, and he lied about it. He's lied so much throughout our whole relationship. About absolutely everything, important things and even things that don't even matter. For example, if he asked the pharmacy if he could have his prescriptions filled and picked up at any of their locations. I'm not kidding. That was literally an argument we had. No joke. He lies about EVERYTHING!!! Anyhow, even with me knowing all that I still chose to marry him. Well, come to find out he was sexting a girl two weeks before he proposed to me, but I didn't find that out until AFTER we got married.. Over the years (currently been together for almost 5 years and married 2 of those 5) we've had several falling outs, but so far 🤞🏻 I haven't caught him cheating, so he's either stopped or he's just gotten sneakier about it. Anyway, a few things happened and we've had to move back in with my folks. The first time we lived with my folks he took and took and took until he got my parents deeper in debt. Anyway, one of the conditions of us moving back in was that he wouldn't do that again. He's slowing starting to do it again. It's making my parents and I furious!! And to top it all off when we confront him about it he lies. I'm just at my wits end honestly... I've separated from him a time or two before because I was at my breaking point. I'm just about there now, honestly. I just don't know what to do anymore. He won't listen. He keeps lying. I don't believe in getting a divorce when a couple has an argument because you just will argue with your significant other at times, but this is all the time about something. I don't necessarily want a divorce, but I don't want to live the rest of my life like this either... I can't keep filling the husband and wife role myself. A marriage is supposed to be a two person job, and I feel like I'm doing it myself. He's gone to counseling, and I've gone with him a few times, and it seemed to be working at first, but now it doesn't. I feel like he stopped trying with the counseling even though he's still going. I was watching a show earlier where this girl said she can't remember the last time she was happy, and that made me think... I guess I said all that to say this, I honestly can't remember the last time I was truly happy. Like, deep down happy.... I'm feeling so down, and I just need some words of encouragement...

P.S.- Thank y'all who actually read through this whole thing. It was long, and I'm sorry.
