Help!! Please read...

My husband of almost a year (that's right, only a year) is a compulsive liar and is starting to show abusive behaviors. I have tried just about everything I could think of to get him to get his shit together, but he just recently got health insurance so I haven't been able to find him a counselor before. Should I tough it out and see if they can help..? Or divorce him like I've been telling him I would if he continued. I'm honestly so fed up... And I am also pregnant so that complicates things a LOT as I'm sure you can all imagine... Please, don't be mean to me, it's been a really hard time. I'm trying the best I can and am just looking for some help, especially from anyone with experience in this type of awful situation. I feel so stuck and hopeless.
