Long story short I've been with my boyfriend for almost 3 years. We have a 6 month old together, I have an 8 yr old with previous ex and my bf has an 11 yr old and almost 21 yr old with ex wife. My boyfriend 11 yr old is very nasty, and disrespectful to me and isn't the nicest to my daughter. She gets excited to see him and hangout but when he comes over he could care less about her.  Its quite sad. I have rules in my house.
