i agree with the other posters, is he still working 3 jobs? if so, that is too much. he must be exhausted. [As Dr. Ruth would say - "stress is not good for sex!" So true!!]

also, what is your response when he says that he "sees you has the mother of his children and he feels like he can't do the nasty stuff with you?" i suggest you answer - "i want to do the nasty stuff with you for the rest of my life!" you might also consider something along the lines of "lovemaking isn't nasty - it's necessary!" maybe all you have to do is challenge these negative comments and express how you feel about him. i am not fond of the reply "get over it" - it does not sound helpful. i think he needs to hear your feelings and perspective on your love life. his reply to that should be very telling. keep us posted.
