Let him and ex wife (?) pay for their daughter's private education. If they can not, it is tough tiddly
If the ex wife (?) is also the mother of his son, let her, and him pay for their son's private education. If they can not, it is tough tiddly.
(They are both working and he will be living for freeeeeeeeeee with you. They can work out their budget based on this.)
If the mother is someone else, let her and him pay for the son's education.
If you are marrying this man and adopting his son - you and (then) DH pay for his education.
You continue to pay for your son's education; put the money in to an educational trust. Romance will turn your head to moosh so do not let even you get in the way of paying this.
Do not live together until married (not with this man)

Write your will and set up Trusts for your son. Update as and when necessary.

This man is a wannabe-cocklodging go-behind-your-back-set-you-up-use-you-take-all-your-money-planned-with-other-women-need-I-go-on?-
pisstaker really.
Yes. Yes. You love him. You are soulmates yadda, yadda
But it is the smaller amounts of money (the day trips etc) and how he handles that; he does, after all, work. He can pay his way. He chooses not to.
You are the perfect mark or patsy. Except you did The Clever Thing and came to us vipers at MN to give you a virtual slap on the chops.
