Eenee, I think it's time for harsh measures to make sure you get your rest and some headspace from your DH. I think YOU need to tell him when he's going to the spare bed. You decide what night he'll start and tell him that you can't have him waking you up when you have hardly had any sleep and you are just as important as he is in the functioning of the family (I know my DP likes to point out how important he is for bringing in the money, so I tell him that it's a bit pointless if I'm not able to keep us running on the home front...a point he is understanding now that he's had to pick up a lot of the slack with me being out of action so early).
It's time Blame the hormones - I mean, he's left you for that hormonal influx period, and if he thinks he can just escape it and come to a made home he's got another thing coming!!
