A real dilemma?

If you have a loving relationship (for several years) but bf has issues with the truth when it comes to money, do you give him a 2nd chance, a 3rd chance, etc.? I have been proactive in verifying the truth and in most cases, have learned he is either really slanting the truth or outright lying. I really love him and I do believe he really loves me to his core BUT do I really have a future with him (i.e., living together)? In the last lie, he was using funds which belongs to his parent but he is authorized on the account for something which wasn't a necessity and he doesn't pay that bill from his own funds (even though he has his own money to pay his own credit cards). When I asked him about it,he said it was debited from his own account; when I asked for clarification (because I knew it wasn't debited), he tell ms how he "made it right" (he deposited the money he used into his parent's bank account); and he says the truth must prevail because our relationship is worth it; that he is and will be the man "I want him to be" and give me love and security the rest of my life. I am a forgiving person and I really love him, but how long do I let this go on???
He further said everyone is different when it comes to money and he didn't think he was doing anything wrong and further, it slipped his mind he used his parent's credit card for 2 dinners.
He then brought up when I dated someone else during our last breakup (I broke up with him due to financial lies on his part) but it lasted a bit longer until I was sure we were back together. He says I probably dated others and hid it from him (not really true). I asked him if 2 wrongs make a right? The difference is I admitted to it and said I was sorry, but he has lied about his finances for several years and tells me he did so "to keep me".He said we are ready to move in and get married; am I setting myself up for misery?
