Re: DH not being supportive...
I would listen respectfully to your husband's concerns. While I think he is wrong that breastfeeding is causing the night waking and clinginess and a "lack" of sex drive, concerns about night waking, clinginess, and sex drive are valid ones and they need to be addressed.
He just makes me so upset, saying that BF is causing her to not sleep at night, making her clingy to me, and the cause of my 'lack' of sex drive.
I think that men often feel driven to "do something" about a problem, even if what they want to do is the absolute wrong thing. Perhaps the reason your husband wants you to wean is just so that he feels like "something is being done" about the problems he perceives.
I would buy some pro-breastfeeding books on infant sleep (I especially recommend Elizabeth Pantley's The No-Cry Sleep Solution) and leave them around the house. Ask him to read them, and ask him for help in implementing the techniques in the books. That way he'll feel like the sleep problem is being addressed- and hey, who knows, maybe it will work!
Regarding the clinginess, I think you and your husband need to discuss why clinginess is a problem. Does he feel like your baby is not bonded to him? Does he feel like you are the only one who can comfort her? Is he afraid that your child will grow up to be too dependent on you? If he perceives specific problems, perhaps you guys can come up with ways to address them that do not include weaning.
Finally, regarding sex drive- whatever is causing it, it sounds like your husband is feeling a lack. Maybe find out what his minimum daily requirement of sexual contact is, and try to find a way to narrow the gap between what he wants and what you want.
