I am currently in a relationship with a great guy. He has everything together,his finances,retirement, and his goals. We are both 49 and divorced. His divorce was fair and he is still friends with her.Mine not so(he took all the money from our home and left me with debt I didn't know we had) so I filed bankruptsy and have started over. Its been rough and I don't have financially nearly what he does. I haven't told him any of this. We really like each other and I am wondering if I should be up front with him now or wait.

Be up front with him. Tell the truth now. Don't wait.
It is not your fault that your ex left you with this burden.
By telling him now (in a matter-of-fact way... not whiny or complaining) he should respect you for being honest and see you as mature in your outlook on your situation and willing to face up to this challenge in your life.

If he doesn't respect you for it... find out now before you get more involved with him.
Don't wait to find out what kind of a man he is.

How long has this relationship been going on? Do you have plans?? If its early, and your just dating, its not his business.

You seem to know a good bit about his financial status and goals. I don't know the exact time you should tell him about your problems but it can't be far off. If you wait too long it could be a deal breaker for sure, or he could find out on his own before you tell him.
