Umm.. lets see you have just described a whole lot of relationships. Cheer up! even though you're lonely pretend you're not sounds pretty stupid huh yeah I thought so too about a month ago when a dear friend gave me that advice she said men are like children think about it, when 2 kids are playing in a room filled with toys and one child (boy) has a toy the other(girl) wants it, he keeps moving place to place with it, saying get off its mine but when the girl finds a new toy and begins playing with it, the boy finds out the toy he has isn't fun anymore he wants hers then he is chasing after her trying to take the toy. Bottom line if your always asking for his time his attention he says okay one day then right back to the same old the next find something new to do, quit asking or getting upset on the outside in his view, go to the mall or drive around for 30 minutes or go get a manicure visit your family, (dont cook dinner on those days, you are busy, remember) something to keep your mind off what he is not doing with you or for you and I give less than a week he is asking to go with you or for you to stay home & spend time with him. mine does haha but the secret is once he does this go ahead spend the time with him but back to business as usual tomorrow One more thing this is NOT a game dont turn it into that, the time you spend alone where ever it is, this is your time to become comfortable with yourself get to know you, he is obviously comfortable and secure with what you two have stop threatening separation and divorce once you plant the seed it could grow into that, he has never thought anything was wrong till you said that you wanted a separation - that is how i met my husband, his wife said she wanted a divorce he never told her okay or no, he said he was just quiet and asked why, then things kinda fell apart after that, i am glad she told him that cause he is a hellof a good proving a great husband and father what was she thinking.. think about it EVERYTHING IS OKAY, HE WILL COME AROUND and dont ask for something you really dont want good luck

Yes you're doing something wrong but don't feel badly about it. It's something a lot of women do. Stop trying to change the man you fell in love with into a different man. Either accept him for the person he is or find someone acceptable to you.

my ex b/f was like that! he would turn me down when i would run and hug him when he comes home. he played video games and hung out with his friends. if he had problems he would tell his friends and not me.
some men dont know how to be good communicators. have you thought about counseling (church)? ask him more questions that he would have to give you a better answer. for example what are three things that you think i should change?
what's great about this relationship is your not arguing everyday. peace is a wonderful thing! you have to get into his head and find out what's wrong.
even though guys dont appreciate some things we do for them. i think you should try to set the mood. for example do you have lingerie, candles, soft music, his favorite meal/ dinner.
