When does it become too many lies to be financially faithful?

BF of a few years continues to lie to me about his finances. While he has become more transparent (b/c he knows I can find out without him), he still lies about certain financial matters. In the last episode, I caught him using his mom's credit card - it has his name on the card but the account is under her name and she pays the bills; he promised not to do it again but he thought it was ok since she owed him money from years ago (really?) - she doesn't have that much money saved and lives in assisted living. Now I learned she got a check back from the utility company for the deposit on her condo he just sold and he deposited into HIS account - when I asked about that, he said he buys her things all the time (toiletries, etc.) - why not use her credit card then? We really love each other but do I really believe that he is changing for the better and will be financially faithful? He wants to marry me and said no; so now he said he'd at least want to live with me by this summer. He said he used her card a few times when he was unemployed for gas and some groceries and will never use it again. He hasn't paid off her bill but says he will do so this month (with her funds). Finally, he told me we belong together and I have shown "him the way" and he has improved and will continue to do so and not make stupid financial decisions, be truthful, etc. Do you think he can change? He's already 65 y/o. Should I move forward or call it quits?

this post is a follow up to a prior post from a few weeks ago and is based on numerous conversations I've had with my bf.

"We really love each other but do I really believe that he is changing for the better and will be financially faithful?" Nope. And you'll be next. (What a shark, to do that to his own mother - not just once, twice, but REPEATEDLY. Bleugh. The fact you appreciate how reprehensible it is *proves* that you deserve - AND WILL ATTRACT - so much better.)

PS: Stooping that low - what genuinely fine qualities *can* he have? What is it (and this is not a rhetorical question) holding you back from being capable of 'dumping the' - based on your own, perfectly logical and sensible reservations as, note, refuse to go away - 'dud'? Have you tried surfing the net regarding financial theft, appropriate and theft and what it tends to belie?
