amy's answer is all about how the op put three people in the marriage, not about how maybe the husband is an ahole, and maybe everyone got married too young.
Dear Amy: My husband very strongly dislikes my best friend.
He feels that she is a "bad influence" on me, as she is still dating and hasn't settled down in her late 20s, goes to a gym that offers "pole fitness" classes, and had an abortion a year ago.
He also knows that I confide in her when he and I have a bad fight or I when I need to vent about something relating to our relationship. She and I have been very close since before he and I started dating, and have known each other since we were in elementary school. She is always very supportive and I try to be there for her.
I am relatively newly wed and love my husband, but relationships are hard and I feel justified in having someone to talk to about problems I cannot always discuss with him.
He is always angry when I am talking to her on the phone and has gone so far as to hack into my email account and read our emails to one another.
Heaven forbid the email contain a reference to an acquaintance of ours we find attractive or a (justified or not) complaint about a habit of his.
My friend does not harbor any ill will toward him, but she is frank about her concerns that he can be controlling at times.
I hate having him sulking and angry, but I feel like I should be able to chat privately with my friend.
We have been there for each other through a lot of difficult times, and share a lot of similar views on life.
