New here...needing advice

I haven't been married for very long...my second, her first. She had lost my trust when we were dating when she lied and slipped up and forgot to cover the lie. I made the decision to get remarry and there has been continued deceit, disrespect, and more lying. She decided to meet up with a guy she doesn't know outside of facebook. I tried to bite my lip when this got brought up in conversation after it happened. I nearly had a panic attack to get away from here asap. A couple of months ago I found a lighter in her car when I was changing the oil in it. She had told me that she had quit smoking and also professed on facebook that she had quit smoking for 10 months blah blah days..so I confronted her about it. She confessed but didn't own up to the lie and had every excuse in the book about why the lie was necessary. Not to mention before we got married, she had a habit of bashing me on facebook. I dumped her for it since I have a boundary about dragging personal friends into facebook crap. She had begged me to reconsider and I did. She did it again at the tail end of this week twice. I bit my tongue almost to the point of bleeding, and then I couldn't do it anymore. I confronted her about it. I was met with rage and hostility. This woman is quite passive aggressive and when I made another request to stop airing dirty laundry in public, instead of seeing the damage it does, she decided to delete me. This of which bears similar resemblence to my first marriage to a borderline personality disordered woman. There are times when she grates on my nerves but I either find something to do or just take a few to chill. I've never really experienced a healthy marriage so I don't know what to do. Divorce doesn't phase me and if its what I have to do to stop the stress and dysfuntion then its got my vote. She says she wants to fix it but I've heard that before. Thank you for anyone who offers advice. Husbands/wives....what would you do if your spouse was bashing you on facebook not to mention you cannot trust them...??:scratchhead:
