If you bring the same set of beliefs to this new relationship that you used in your earlier failed relationships the end result is almost certainly going to be the same.
Take some time to read up on successful relationships.
Remember, foreign girls are signing up with Global dating agencies, because they are not happy with their marriage prospects in their home country, not simply to make you happy.
In fact, the whole concept of the submissive mail order bride is simplistic and poorly thought out and it is a trap that can ruin your relationship before it ever starts.
Russian ladies that grew up in the last dreary days of the crumbling Soviet Union had vastly different life experience than young Russian bride who grew up with the internet in a more or less free society.
So, the old stereotype of an Eastern European lady as a pushy, materialistic, green card bride, which was always a gross exaggeration of the worst Russian ladies, is much less true today.
So, give up any overt or subliminal desires to control a younger woman, because this is perhaps the single most corrosive thought that can creep into any relationship and it will almost certainly eventually doom the marriage.
There is nothing wrong about being open to dating and perhaps marrying a younger woman, but do not fixate on it.
First, are you interested in a particular young lady or younger ladies in particular?
If there is a growing mutual attraction between you and a particular younger woman, regardless of a large age difference, that is probably a good thing.
And recognize that she is going to grow and develop throughout your relationship, in fact, whether you are twenty-five or eighty-five, so will you.
