me and my partner have a 9 month old son and had a very healthy sex life before she fell pregnant (3 or 4 times a day),i understand that sex wouldnt be on her mind as much during pregnancy and i dealt with that but our son is 9 months old now and i can count on one hand how many times we have done it,our son goes to my mums 1 night a week and she sees that as "our chance" but she seems more pre-occupied with watching soaps than spending time with me in bed,she seems to think that the second she says "lets go to bed" that i jump up and am "up for it" (which i'm not 99% of the time,therefore leading to non-performance),i have tried talking to her about it and been honest but she turns it round on me saying things like "you obviously dont find me attractive anymore" and "i obviously cant turn you on any more" etc, it doesnt feel like i am in a relationship with her,it feels more like we are housemates who had a baby than in a loving relationship,what should/could i do to change the situation ?
