I think someone from OH's work fancies him (who can blame them) and I don't know why, but he's suddenly become very secretive of his phone. I have this feeling that he's egging her on a bit. She was texting him on Sat night and near enough all day Sunday (I only know this because I was playing bejewelled and she texted him and I was nosy ?), anyway, what has got to me was that I was babysitting my niece at my sister's house on Saturday night and he barely texted me.
I don't know how to react really.
