Have finally managed to catch up! You lot were chatty last night 
Sleep training. I am lucky in that O tends to sleep through, but he cannot self settle for shit. On Friday night it took me 45 minutes of rocking and my back is fucked. It doesn't usually take that long, but this current developmental leap is making things difficult right now. So, I need to work on self settling. Any tips? He can do it during the night so can do it.
Some lovely wedding talk. Having been engaged twice, I have started to plan two weddings, however that has sadly made the idea of marriage less special to me than it used to be. I genuinely don't see myself getting married at all now.
Oh Sophia ((((massive cuddle)))) Your situation must be so difficult for you. You come across as such an incredibly wonderful person and I am certain that your DD's know that too. I have a lot of hope that all of your babies will be under the same roof at some point x
Evil ((((huge cuddles)))) for you too. I have many of the same fears of you. At the moment XP is being remarkably civil but I am dreading the day he starts demanding more access to O (He currently has him all weekend) or the time O tells me he wants to go and live with his dad. O lights up when he sees his dad and loves his time with him - which is what I am trying to keep in mind - but XP always gets to be the fun parent and seems to have plenty of money to spoil him (not surprisingly as he only gives me £20 a week for O). But our boys will grow up to be very proud of us - I am very sure of that. You are an incredibly strong woman and deserve to be proud of yourself.
Isles I agree with Lily et al regarding rent. In your situation I would do everything by the book and let your landlord hang himself, so to speak.
Erm, I'm sure I had more to say but my mind has gone blank. A bit more info about new guy - he is a theoretical physicist 
, very funny and very lovely.
