I was the same, its like everything in your life has changed, been turned upsidedown.
I found it got better when Corey was about 2 months and was going to bed at 8pm til 5am instead of 10pm til 5am, because I'll go to bed at 10pm, as I have to feed him at 5 (tho he does go back down til 8 ). Well that meant no time just me and him, always had Corey to be dealing with, feeding, changing, playing with etc etc. Where as now, we have two hours in the evening to relax, watch tv, or a film if we want to... its nearly like it used to be, except we have a perfect little boy upstairs!!
6 weeks ago, I couldnt even imagine it being like this, I thought my life was over. It will get better hun, at a month old your LO is still so dinky, that you need to give alot of your attention and time that way instead of to your DH!
