Virtually everything you mention will stay the same (or possibly deteriorate, who knows), if you give up BFing. That's not to say don't if you want to, but I think you are focusing on it being pivotal to all these things, whereas your problems can be reduced to 2 things:
-
the reality of having a baby. What you describe is totally normal. It's incredibly hard, but there it is. I don't mean to sound flippant, because I know it can seem so overwhelming at times, but a baby is what it is. If your baby is very clingy, taking away her primary source of comfort, your breasts, is going to make her more clingy, not less. Your feelings of needing some time to yourself, but missing her if you are away for even a few mins, are also completely normal. You need to hang on in there.
-
your OH is not pulling his weight. Do not fall for the whole 'I'd do more if you weren't BFing' bullshit. If and when you give up, he'll must find another excuse to let you do virtually everything. Going out and getting hammered, meaning he'll be neither use nor ornament to you for the rest of the day, when you are so exhausted and overwhelmed is really thoughtless and unacceptable.
I would suggest that, if you haven't, you try expressing, so that you can see if he'll put his money where his mouth is, and give your DD a bottle (of your milk). I used to express, and store milk, so my DH and parents could give my DS a bottle when I needed a break, sleep, etc.
Or, as magoria suggest, you could always mix-feed - breastfeed, but also give formula at some times. Then others can try to give her a bottle.
If you've not, seriously consider getting a sling or baby carrier, so you can carry her next to you most of the time, so she gets constant contact, and you get to do more stuff and have your hands free. They really can make a world of difference. Your OH can use it too, obviously, which will free you up.
I think though, you need to have serious words with your OH about his priorities, and also about finding ways to support you if you have a velcro baby (like providing you with food and drinks, making sure you are comfy, babywearing, lots of things), instead of blaming BF. Good luck.
