Recently separated, legals all signed and nearly completed. Have had an agreement with ex re kids that was working reasonably well. But recently he's taken to making small changes to arrangements and communicating these via the kids. He also goes crazy if there is anything missing when the kids go to his place, despite similar happening when they come back to me. Yesterday he was verbally aggressive on the phone cos one of the kids had forgotten their jacket and then texted me saying that I 'needed a lecture'. He messed me about last night over dropping off my daughter. Originally I had arranged to drop her off earlier, then she said her dad was coming to village where I live anyway so would pick her up but later, then he texted me later still to say 'thought you were bringing DD over'. My DD would not be lying, 100% sure of this. The complicating factor is that she is less happy about going to her dad's so I feel bad saying to her 'no you can't come home to the house'.
I had arranged for my (male) friend to come over. We were planning to have a bit of time together but ended up with my daughter and then having to drop her off at her dad's. (I had previously got it all planned - I put the kids first, every time). Actually the time with my daughter and my friend was really nice...but just not as planned and i got the feeling that my ex was deliberately messing me about. After I dropped her off I got a text back from ex saying 'thank you and your friend....friend....go-karting friend for dropping off DD. Friend ;-)'. It's wound me up a bit. I have been open to the kids about the end of my marriage and by the way I was always faithful, unlike ex; and about my new friendship...and I call it that because it is not a relationship at this stage. They are always welcome at my/their home and I would have them 24/7 if I could. I do think that it's reasonable for me to make arrangements with my time though when they are due not to be with me.
Should I confront ex or just ignore him? At the moment I'm ignoring and only responding on factual points - re practical arrangements etc. Sorry post is a bit long.
