...it's not easy.
My ex (we've been separated for about 14 months) seems to have been going through partners at a fair rate. For example, I gave up my Christmas day with our kids because my ex would have spent the day alone and I wouldn't wish that on anyone, only for them to suddenly announce that there was a new partner who was staying over and would be spending Christmas with my kids. They broke up a few weeks later.
Anyway, fast forward to now. The kids were staying with my ex this weekend just gone. I get an email from my ex just before the kids come back telling me that there's another new partner and that this partner "popped in during the weekend, and met the kids".
When the kids came home, I got the full story. This partner had actually stayed for two nights over the weekend (so much for 'popping in'), and the kids had no idea that this was going to happen. They had also never met this person before.
The kids were also sad that the last partner wasn't on the scene any more.
I have no problem with my partner meeting other people (although I do pity these other people... heh), and I'm pleased (in a way) that I'm being told when there are new people in the kids' lives.
However, I do think that springing a new partner of no more than a week or two on the kids for a full weekend visit with no warning kinda stinks.
Or am I being too sensitive?
