After reading your post twice I'll be honest and say that it's never going to work.
Too many break-ups. You seem more needy than he does and his use of a few endearments isn't a strong enough basis to support a normal relationship.
The fact that you rushed into intimacy and over-valued the words he spoke, tells me that your late DH wasn't the same kind of man and this 'new' impoverished artist cum journo has bowled you over with a kind of romantic, attic-artist laissez-faire attitude.
You are in danger of paying for love and romance (often not meant) with your money and other generousities.
Please take off the rose tinted specs and make friends, learn about the people you interact with and if you meet someone in future, dig into their background - Google is your friend.
Keep your money and property firmly behind closed doors. Don't tell everyone who talks the talk and makes you feel special.
When they've got what they want you'll be left poorer, in more ways than one.
It may hurt for a while but a knock now is better than a stab in the back down the line.
Best wishes and count yourself lucky.
