Everyone loves my fiancee. EVERYONE, you can't stay mad him at all he's nice charismatic, sweet, flirty, fun... just everything you want a man to be......infront of other people only but not me at least not anymore. As soon as our guests leave or we are alone for a long period of time he's the exact opposite. He's very quiet, introverted, boaring, depressing, angry, pessamistic, cold, and even argumentative. He has this incredible front for all to see and it's actually a little disturbing how dramatic the difference is in personalities. This isn't the romantic wonderful man I dated at all. I feel like I've been gipped, I hate when people leave because I don't want to be alone with him....it's sad horrible and depressing for me he drags me down with him. When I ask him what is wrong he say nothing and he gets angry with me for even asking or if he give me an answer it's "you're reading into things, leave me alone". My sister moved into our house 6 months ago and she has noticed this behavior as well so I know this is not me. What is wrong with him?  I know people usally have a face they wear in public but this is nutts, nobody even knows the real him. Is it me, does he just hate being around me? Is this who he is? Am I stuck with this crazy mulitple personality Phony person....what is wrong here? I don't want to spend my life depressed alone and in the dark with this man.

Please help
