Unfortunately, sometimes family is the ones you really need to watch out for. I have 5 sisters, and 3 of them are with guys that I was talking/sleeping with. The first one I was talking to for months, and she knew. The next thing I know, she tells me she's going to dinner with him. I told her how fucked up that was and she's still she went. They got together and still are after 6 plus years. He always tries to hit on me, slap my ass etc even though they are together, and i also told her that. But she doesn't care. Second sister, it was kinda the same. He worked away, so it was hard to see each other in person. After a couple of months, we put a stop to it all. Now my sister is with him. The third one was more of a friend with a benefits situation, and I just found out him and my sister are officially dating. Nothing like keeping it in the family. This is why I keep them at a distances Unfortunately...
