everything is not normal these days

Well today i woke up and my day started off with my mom telling me that my Grandmother had said something to her. My grandma told my mom that my future step sister was flirting with my husband. I have already mentioned this to Franco a couple of times. But he acted like i was just being jealous, but i swore that i wasnt,but i let it go. Then when my grandma and my mom both said that they thought the same thing without me saying anything to them before. See this girl(i dont want to mention any names) she was raised in a horrible lifestyle. Her dad and mom were very open about cheating on each other for many many years. So she is pretty messed up(not being mean). But i mean she is very open about asking Franco and only Franco to go outside to smoke,but he doesnt smoke. She doesnt even ask anyone that smokes. She always flirts while we play board games and even at the dinner table with everyone there. I am so confused. I dont want to be mean trying to get her to stop without starting a fight,but i dont know how. I want to be angry really angry! She is like my sister, i have known her for 13 years! She and her mom want her to ask if she can live with Franco and me,but i was like nope not happening! HAHA! I mean i know that girls are going to flirt with him,but she knows me very well and she know we are married. It is extremely different and twisted in my view. I dont even know how to put all this because it is really messing with my mind knowing that im not just being jealous......i just dont know i mean what would you do having to witness that every week........your stepsis flirting with your husband. I also had a weird dream the other night. I couldn't get it off my mind. I ended up looking into interpretation of the dream. It ended meaning that someone was having intense or repressed sexual desires, someone close to me was going to betray me,and that there were some strong emotions going around and i might be to nice to people that might hurt me. Isn't that weird though. Maybe i am overreacting but everything is going weird this is all stuff that was happening and now it is falling together in a very bad way. This is so wrong,but all i can do is hope that she doesn't try anything and trust Franco with all my heart like i promised in our vows.
Anyways now to the rest of my day....I went to work arounf 8:30. I was having an off day all day long(it was my monday). But i was getting by. Well it was extremely cold and raining so what does that mean at my work????? Tons of heating units froze and running on emergency heat( way expensive...my moms had to do that our electris bill was 297 last month YIKES!!!)! So everyone was calling and that was on top fo everything normal. Well then about 230 it was dead and then at 430 it got swamped! I was suppose to get off at 5 and didnt get off till 545 and i still wasnt done,but was told to go home anyway! I went out to my car and my door was froze shut! WHAT A DAY! lol.....but it could have been worse.....remember it always can get worse!

I just dont know what to do about that whole dream/sister extreme flirting with my husband......any advice??????? I love you all!
