I'm in dire need of a place to vent.  Also, does anyone know the protocol if your SS is just 18 as far as whether he's considered an adult or teenage step at this stage?  

I feel like I just need people to talk to and feel that this place even though I don't know anybody might be the best outlet for me. I have been married for four years after dating my wife for two years. My stepdaughter was eight when I came into the picture. It was super easy in the beginning. We were more friends than anything but slowly but surely that has changed in the years since we have become a family. It is easy to chalk some of it up to the fact that she's a teenage girl. Part of it can be related to the fact that my wife and I have had some marital struggles.

This is what DH said about SD13 last night while we were discussing the evening's events. Here's the recap:

DH and the kids (SD13 and DD3) get home. DH and DD say hello; no hello from SD, which has been the norm for a while. 

My husband and I have been married for 3 years. He has 3 kids: 22, 18, and 15, and we have two babies together. I get along with the older two just fine (the oldest is on his own) but my SD I can't stand and I feel awful for even saying that. Our relationship started off fine but early on she would steal any and everything from everyone then lie about it even when she got caught. She's very loud and loves having the attention on her. She picks fights and is so disrespectful to everyone. Now, she can be helpful and nice but I always question whether or not it's genuine.
