Another thing is the circle of friends – you should not make your younger boyfriend hang out with your friends, or you should not keep away from his friends.
You should take care of your partner, but not too much – remember you are his wife, not his mother. Let your man be the main character, and support all his decisions. If he wants children and you want it, do not wait too long.
And last but not least – age is really just a number. Love, passion, and mutual understanding are more important.
