This has to be a wind up by a pissed teenage boy surely?!
2 o'clock in the morning? 
We haven't had a night out together in a year - Goodness a whole year, and I bet you can't even take turns to go out out with friends what with having two parents living at home and all.
And even then it was a 'must be home for midnight' affair what terrible hardship you must be traumatised - having to be in by midnight.
They share childcare between the dcs father/mother ummm and given you have two parents at home, you can't do this because.....? You don't even have to take the children anywhere or deal with them crying because they don't want to go or deal with an ex being abusive to you when you drop off. Just take it in turns and hey presto, problem solved.
don't feel I know him - why on earth did you have 3 children with someone you don't feel you know. After 10 years... really?
You sleep in the same room/bed?
I have no weekends off, I go to football on saturday morning and rugby on sunday morning I get not one lie in ever though it is getting easier now that DS is getting older. Oh and the joy of dealing with an upset vomiting child when you've got the same bug in the middle of the night.
I've had 3 proper dates (with the same person) in 8 years and one half arsed "relationship" - all of this was during the day because frankly it was just too much hassle trying to arrange babysitting in the evening. I don't think I can remember what midnight outside of my house actually feels like. DS had his first sleepover recently and I did nothing except stay at home because I couldn't think of a single person I knew who was available to come out with me who wasn;t in a couple. Married couples don;t (IME ever invite single paretns to anything in the evening).
Babysitting partly a hassle because I support myself and DS, no other income except courtesy of HMRC so babysitting is a luxury which I have to think through carefully. SO do be prepared to give up a chink of your income too.
I chose to do this and DS is certainly worth it and you won't find any whining threads from me about how hard it is. And as someone upthread pointed out - if its so very attractive then knock yourself out and split up.
Do come back and let us know how that works out for you.
