Hi and welcome @Jena mullan.
Actually, you could have stopped at that point. There was no need to go on to "know him better". Once a guy accepts woman's money it becomes clear who he is.
Good for you you kicked him off.
Unfortunately there are no rules.
We can get fooled locally, internationally, virtually... Some ’men’ are disgusting pieces of brown substance, wherever they come from.
If it was just for the money that could be managed. When feelings are involved, it takes so much more to move on.
