I am curious as to how some of you may take this? Got this from my girlfriend.

Her child was having all their wisdom teeth removed. She called me at work to tell me when the appointment was the following week. "I'm gonna take Tuesday off and take her she said, should I take Wednesday off too?" I said yes, she will be in pain and if she needs someone there Thursday I will take off. As I said I was at work so I had to get off the phone kinda quick and said we will talk more tonight. A few minutes later I get a text that said,"no you don't have to worry about going with us Tuesday just go do something with your real family!!!!" I was at a loss. My real family? I had been living with her for 3 years and when she worked nights I was the one taking care of her child!!! How could she possibly even think that I didn't think of them as family?? This isn't the only text I have gotten like this over the relationship
