My partner (M, divorced) and I have been seeing each other for 6 months. He has two kids aged 5 - 8 who I have not yet met (but they are aware of my existence). We are very much in love and he is about to move in to my home and is ready to introduce the kids to me, slowly over the next 8 weeks, with a view to them coming to spend their few nights a week that they have with him, in my (our) home. Both of us would be there, which I realize needs a slowish introduction for the kids. But his ex-wife is demanding we should have lived with one another for 6 months before the kids meet me and is refusing to allow the children to stay. The options are that either they can't see him, or I have to live in a hotel 2 nights a week (week nights and I work during the week) for the next 6 months. I have no idea what to do! I don't want to stand in the way of him seeing his children, but it's also completely impractical (and expensive) for me to stay elsewhere for that long. Is his ex being unreasonable about this? What can we do to reassure her? She is pretty bitter about their break up and what she sees as my role in it, so I'm worried she's never going to accept my role in her children's lives (as someone who supports my guy to be the best Dad he can be). Help!
