I have been in a relationship for 4 years with a guy who's not my kids biological dad. He gets on well with them and says he sees them as his own, especially the youngest who was still a baby when he came on the scene. The thing is when it comes to anything to do with the kids from getting up on a weekend with them to making their pack up or reading their school books it's all down to me. He claimed he sees them as his own children but although we both work he still expects me to be the sole care giver and does very little around the house am I expecting too much or if he's living with us and we are both busy people should he chip in a bit more with the hands on stuff.
