I started seeing someone around June last year. He was a single dad with a 10 year old son. He seemed great, we met up for coffee, enjoyed each other's company and it gradually got more and more serious. I met his son who was a typical 10 year old lad and he met my typical 10 year old lad. It all seemed "too" perfect. Which means it probably was, I know. I'm a full time nurse and he is a market trader. This means he more or less chooses when he works but obviously I can't be quite so flexible so he's started comming out with little snipey comments about my work. "Don't you find it restrictive? working set hours let that?" "we never get any time together, you're always working" "if swine flu goes around again, we'll all get it because you'll bring it home from work" 
I live in a 3 bedroomed house and he lives in a two. Therefore when there was talk of co-habiting it made sense for it to be my house that we all lived in. So he and his son started spending more time around here, sleeping over the odd night/weekend etc and this experience in mind, I think I'd be mad to move them in. His son literally sits glued to Nickolodean all day or Grand Theft Auto, my son then asks why he's not allowed to play on 18 games. DP says I'm too strict and should relax a little. DP thought it would be a laugh to put a used condom on my pillow one night because I'd refused to dispose of it for him. Yesterday the pair of them walked mud all through the house and he never even offered to clean it up. If he makes a cup of tea, he just leaves the tea-bag on the work surface instead of putting it in the bin etc etc
Thing is its not just the moving in thing I'm having second thoughts on, its the whole relationship. At the moment DS and I are finantially stable, have a nice house and live a comfortable life. I can just see all this going tits up if I get any further involved with this man and his son.
Im not being too picky, am I??
