i went through the saaaammmee thing. when i was 2 1/2 months pregnant, my husband and i took a trip to europe together and i was miserable and just wanted to get away from him. the smell of him (as you said), hearing him talk, everything...
now (i'm nearly 18 1/2 weeks pregnant) i cant get enough of him. im so in love with him, like always. it will pass, my dear. i promise! just keep telling yourself that it will pass and try not to make him feel bad for just being himself. believe me, dont push him away, you're gonna need him!
