Entity Framework 4.1 Code First Self-Referencing One-to-Many and Many-to-Many Associations

I have a User that can have collection of users he likes...

Another user can have collection of users he likes....

If User A likes User B and if User B likes User A, then they get to hang out. I need to send each other their contact info. How do we represent such a model in Entity Framework Code First?

public class User
{
    public int UserId { get; set; }

    public int? UserLikeId { get; set; }
    public virtual UserLike UserLike { get; set; }
}

public class UserLike
{
    public int UserLikeId { get; set; }

    public int UserId { get; set; }
    public virtual User User { get; set; }

    public virtual ICollection<User> LikeUsers { get; set; }
}

Is this model correct? I can't get this to work.

I've tried another way but that doesn't work too...

I tried to add collection of user to user table.

For ex :

public virtual ICollection<User> userlike { get; set; }

public class User
{
    public int UserId { get; set; }
    public virtual ICollection<UserLike> UserLikes { get; set; }
}

public class UserLike
{
    public int UserLikeId { get; set; }

    public int UserId { get; set; }
    public virtual User User { get; set; }

    public int LikeUserId { get; set; }
    public virtual User LikeUser { get; set; }
}

I get this error when I try to add user and who they like:

Conflicting changes to the role 'UserLike_LikeUser_Target' of the relationship 'UserLike_LikeUser' have been detected.

What's the best way to represent such a model?
