You can now do whatever you want....
You not realised that yet? he doesn't own you any more..... [hgrin]
so what are the time scales here? What's your story? [nosy]
If you are looking to get involved again to replace DH, I'd caution against it. You need time to heal, to realise who you are again and to love yourself. You need to forgive yourself for everything that went before, love yourself, respect and know yourself. You need to do all that before you start another proper relationship.
if it's a roll in the hay.... what the hell, go for it! be safe, respect yourself and don't put yourself in any danger though, goes without saying.... Make sure DC don't know about it.
We had a troll thread on here the other day about a bloke that was involved with a woman and her kids in 3m, and the consensus was broadly that this was way too soon, and that the man/woman relationship needed to be kept totally separate from the DC for a heck of a lot longer than this guy and the love of his life had done.
