My boyfriend, Aaron, has a daughter with his ex girlfriend whom he was with for 5 years. When they split up when the baby, Jay, was a year, his girlfriend got full custody. He was going through a teenage fuss and had another girlfriend so she demanded that she take full responsibility for Jay. He continued to support her financialy and, on ocassion, saw her and their child.
Now, he's in universtiy and has cleaned up his act. He still sees Jay once in awhile but he wants to be able to spend more time with her. She's six now, in grade 1, and she wants to spend more time with her daddy. Her mother is open to this exept one thing: I can't be around. Aaron and I have been dating for over a year, I've met his dauther once (she fell in love with me and accidentaly told her mother that

, so I know that she must be feeling like she's be replaced) and I've only met his ex once as well.
I'm all for them spending time with eachother, but I'm worried. I feel left out from part of his life. I'm also angry because her boyfriend whom she has another child with, is not exactly father of the year either. But why is he allowed around the children but I, a pretty damn good individual (i think!), have to keep a distance?
My boyfriend is afraid to fight with her on theses issues because she does have full custody and has the right to say no. What can I say or do?
