Beautiful widow with 4 kids?

I am 30 yo lawyer with no kids. Have been dating for 2 months a 36 yo mother of 4 who was widowed 2 years ago. There was chemistry right away, and I thought I would give it a chance. She does a great job as mum. I love her kids and they love me (theyre all girls). I really half love this girl as well. as you would expect she has demands from her kids and is not good at fending off her friends kids/ friends. I think I have been a v good boyfriend as I have accomodated her cancellations and I go with the flow and fit in with her routine. The trouble is that because of all that its pretty one way. I feel I have taken a look at her life and she should now reciprocate. she wont have anyone babysit the kids except her 17 yo who lives out of home. the 17 yo is moody and erratic. We hardly go on dates. But when she wants to show me off to her friends it happens. I want to go on dates, and I feel she is jeopardising the romance and hence the whole thing. The kids are attached and I am worried about the fallout of a ill thought out break up. This girl is lovely and quite switched on but I have found when I have brought up legal issues have had she takes an opposite view and I find it less than supporting even though she means no harm. I am just worried about it given that she hasnt yet bothered to look into who I am. I am more about books movies friends thinking and she is more about kids talking with other mothers about kids, nuts and bolts things. I feel I am learning from her but she not so much from me. I would like her to watch a movie I recommend but its not something she will do. What do you think? We really like each other and she wouldnt know I am thinking this and my experience is she cant take any angst probably due to the bereavement 2 yrs ago
