it sounds like you are missing him loving you...... if he doesnt start loving you again the love will go away.
you sound a lot like me when i was younger and I can tell you that a lot of men just dont return or need love in the same way as we females need and want it..... but it does not mean they do not care, they are just different --try to learn how he shows his love and appreciate him for it. (my husband loves through doing for me)
Oh dear. Take a break.
iv never been in the situation but, probably when u begin to feel less interested.
