What would you advise?

i am in a situation that makes me sad. i have worked hard all my life to get my flat and save some money. i am 33. i met a man who is 40 who is mively in debt because his ex wife lied about them buying a house and pretending she earnt a fortune from her business. she is bipolar. they are divorced and it is bitter. this is all true as we have friends in common and i know his family. he wants to settle down and have a family longterm but i'm not sure i could face having to help pay off these debts knowing they were bought on by their extravagant lifestyle because she lied about how successful she was. (she was a tax expert and in charge of their finances, he was naive). the trouble is i do find him funny, sweet, faithful, kind, attractive...and know these qualities can be hard to find. but i'm not sure i can stomach seeing the photos of them having this great life and knowing we won't because we're paying it off without feeling a bit bitter. (even if i don't pay it off i will effectively be doing so by having him not contribute). my mum thinks if he's a good man i should accept it...but if i do how do i not feel bitter at all? none of the things i dreamt of will happen (marriage, having money to go freelance/do an ma at some point cos will feel selfish spending money on these things when potentially as a family we will be in bad debt). any advice on how not to feel bitter if i did settle down with him .....or what to do?
