Is it hard to adjust to dating someone with a child?

I dated a guy who had two children...Yes it is very hard to adjust. The thing that was hard for me was the expectation that he put on me. He would leave me alone with them to watch and all sorts of things which was fine but would never say thank you or anything. It was expected. When they were around it was like I didn't exist but to just be there to help with the kids. The thing is that he did not see them all the time so when they came I was pushed to the side. You have to adjust just as much as she does. You have to understand that to her, you come first whereas with her she knows already that she is second. This is already hard. I love kids and got along with my boyfriends kids very well but me and him did not get along very well because he was the type to be like my kids come first and if you have a problem then leave. He never took the time to make me feel like a part of them. I was always this separate thing and you can't be like that. If you want it to work you have to include her and make her feel wanted! Even though the kids are around, she still should feel wanted!
