To me there is a difference in the way I used the terms Drama & excitement. You said that you and your H do some exciting things...like going to museums, concerts, dinners etc right? Well that type of "excitement" can be fun...but it can also get fairly predictable because you are doing it with the same person, fun nonetheless...exciting, not so much after awhile. DRAMA, IMPO...is what this OM brings to your life...he's a contrast to your H, something different, with a different level of "excitement", but he's a problem to your M...therefore DRAMA.
As you've stated before you like a certain level of "excitement"...when life gets predictable/mundane/dull....you get restless. Never said you were a drama queen ;-), to me that's someone prone to hysterionics...I don't think that's you...but this OM stirs things up far beyond where your M would on it's own. It adds complication, it adds spice for you, it adds forbidden attention....DRAMA.
That difference to me is why I said, admit it....you like Drama. Still may not make sense to you, but I do see a difference.
