i wouldnt leave him unless he is cheating on you. i believe in trying really hard before you give up.
my ex didnt appreciate me and he did the same thing. rush me off the phone, was very secretive etc.
after you told him about you lingerie, did you tell him your size.
he may love you, but i was told men get bored fast. if this is true are you able to buy a sexy lingerie. i am a very spontenous person. i would surprise him and dance in front of him with music. spice up your love life.
i also would have a serious talk about what makes you happy, upsets you, things you want him to do and not do.
try to do things that he likes. have a candle lite dinner.
dont be depressed b/c he's not treating you the way you want. stay positive!
if this doesnt work talk about seeing a therapist, even church based counseling.
