Hi blixen, sorry to hear you are having a hard time of it at the moment...doesn't sound like your dh is very supportive. Does this extend beyond the bf/intimacy as well? I mean, does he refuse/resist being involved in caring for the baby eg bathtime, nappy changes, soothing etc.
Maybe he feels left out, or hasn't had a chance to bond with the baby. Maybe you could try involving him more, even leaving the baby with him for short periods if he will agree to it (I know it is hard when they are feeding constantly as you feel you are indispensable!) He is definitely jealous and resentful as you say of the amt of time you spend with the baby, and of course at 10 wks this can't be helped most of the time. I'm sure part of the problem is your tiredness, and if you feel like I did, breastfeeding satifies your need for intimacy and so you don't feel like "sharing" your body with someone else once you have it back for a short while! I'm sure you have tried to explain this to your dh, but he obviously doesn't really understand..which is fair enough when you think about it - he can't really relate to any of it, can he?
Looking at it from his pov (which is not to excuse his behaviour, just to try to find the reasons behind it) he is probably basically just sexually frustrated (which most men cannot handle well at all!), feeling isolated by your closeness to bub as well as your giving to the baby the attention he feels he needs/wants, and feeling you and the baby don't need him since you have each other. Is it specifically about your breasts or is it any intimacy/sexual attention he seems to be after? Maybe your breasts are just his focus on the whole issue since they are the focus of your time with the baby? Some men can't get past seeing breasts as sexual "objects". Is he affectionate to you thru the day/evening? Do you feel he is "punishing" you by refusing to do his share, or by sulking rather than talking about it?
Maybe you could explain that you understand he feels frustrated and you are glad he still finds you attractive and desirable, but you don't always feel that way; suggest ways he could help you to feel more "in the mood" thru the day (ie helping out, giving you a hug or kiss etc) rather than just trying to leap on you at the first opportunity! (Hope this isn't offensive and sorry if I have the wrong end of the stick here!) He might be amazed at the difference it makes for both of you. Sorry to have gone on, but HTH!
