DP and I both have 6 year olds from our previous marriages and an 18 month old together. My dd sees her father usually alternate weekends, DP sees his son every Sunday and full weekends when he isn't working Saturdays. This Sunday dd and I have been given some tickets to a show which my friend is to ill to attend. We were meant to be going to a soft play area on Sunday and although that's a far more toddler friendly environment, dp has just assumed toddler will be coming with dd and I to the theatre.
Similarly, last week he took toddler dd to his mum's while I was working from home. He had a doctor's appointment that afternoon and so bought her home to me first rather than just take her along as I would do if roles were reversed.
Whenever he makes plans with his son he never factors in our dd, it's just assumed I will have her if whatever they're doing isn't suitable for her. Of course I want him to have a good relationship with his son but despite my dd living with us, I actually feel I see her less than he sees his son. Since toddler dd was born, elder dd and I have had one single afternoon alone together. I would love to spend some one on one time with her, and have told DP this, but he just shrugs and says we're all too busy - the thought that he could have toddler dd as well as his son while I spend time with dd doesn't even cross his mind. AIBU to think I shouldn't always be the default parent?
