compulsive lying and love.. help!

I've been with my "boyfriend" for a better part of 3 years. Right now we are split up because I'm tired of his lying and his lack of motivation to keep a job.
I'll start by saying that I am stupidly in love with him and have been since the day we first started talking online. We lived together for a while and it ended up failing because I lost my job due to my car being destroyed by water. We had to move out and separate because we didn't have any other income to fall back on since he couldn't keep a job.
He always talks about his life in Alaska with his ex gf and his two kids. He claimed he worked all the time to support his family and he was treated like a horrible person. He claims the same about his step father and mom. Although I lived with them and him I realized how messed up they are and they raised him horribly.
I recently found out that he's been lying about pretty much everything. Almost none of what he said of his history was true. He has burned bridges that he really shouldn't have. Right now he is sitting in county jail because of back child support and has vowed to me that everything will change. Although I have given several chances to him to make things better, none of which has worked. I truly feel this time it will be better. But perhaps I'm just a fool. He has admitted he needs help and he will when he gets out. He has court soon and it will determine whether or not he will have to do 6 months. I feel like it will do well for him
He can get his GED and maybe get some help and a new perspective. I've been feeling like I'm super naive and things will never change.
after reading some of these threads I really don't know what to think. I seriously love him. He is my best friend. We've been through thick and thin. He's my rock.

Any suggestions?

Thank you in advanced

This relationship is alot like the one that I have with my mother. I support and care for my mother but have alot of issues with financial management and gambling. So my mother manages all of my finances but she can't say no to me when I ask for money to go gamble. If I weren't supporting my mother financially, and she me emotionally, I would say the best thing for both people would be to split up until the problems get better or resolved. We have been working at it for the past few years and have lost nearly everything including our home and are massively in debt. My best advice to you is, if you have no attachments or children with your boyfriend, maybe try taking some time off and see how you do on your own. If you have to have him back in your life, let it be so, but don't just let him back in because he begs for it or asks for your forgiveness. Love will win out in the end too, so your other option is to stay with him and help him look for jobs and get help with his lack of commitment. (And I'm a hypocrite for saying this too because I can't hold a job either.) Best of luck and good wishes to you.
