My boyfriend has a married stepdaughter who will call him for everything. She is totally helpless even though she is married to a man who makes a lot of money. He took a picture of her while she was sleeping during one of his "visits", is this weird or am I being a jealous girlfriend?

I think you are right to be concerned , it is a bit weird , maybe tell him what you think ?

Sounds pretty weird to me. How long has he been in her life? Taking a picture of her while she is sleeping is strange, but that is just me.

Not enough information. Taking a picture, by itself, means nothing without the context.

And a rich husband might be working all the time, even away a lot for work.

On the other hand, she is not his bio daughter.

Just not enough to pass judgement.

Have you discussed their relationship with your boyfriend? Is he aware of how you (or others) perceive their relationship?

It pretty much boils down to whether you feel comfortable in the relationship. You cannot make someone change. They either make the changes for themselves because they see the need or you accept them as the whole person they are. The only person you can effectively change is yourself.

If their interactions became closer to what you think of as 'normal', would you still worry that he might become more secretive instead of letting go or that things would, at some point, return to the way they were?
