change in dynamic

have you ever had the tables turn on you so fast that you thought you felt the turn literally? well even if it's never happened to you, i would recommend you brace yourself for some real live rollercoaster type sickness. you're probably wondering what this is all about. i wrote a story about it, here goes...
the unofficial Mr. came in last night on some real world madness. there were turkey sandwiches and reese cups flying everywhere. okay. not everywhere so much as on the back porch. but you should have seen that turkey sandwich this morning. it looked balled up for real. so he gets to going into his spiel about how he's been fucking up and i've been nothing but the best to him. so his way of proving he hasn't been sexually involved with anyone was to have me go through his phone. i declined because i knew no good could come of it but he insisted. let me just tell you it was all bad. i wanted to hurt him for real, but he decided to go to sleep instead. how tempted was i to slap the shit out of him like the last one...VERY!!! but i held out. instead i sat up all night long coming up with a way to call things off with him as civil as possible. he woke up with no recollection of anything that transpired and i held out on divulging his secrets in his phone. he was just told about the food fight and socks coming offerization. i left out of the room and while i was out; he took it upon himself to go through my phone. i'll admit i was texting my sub after everything went down. even mentioned my desire to take the Mr.'s car and go have fun with him. i held off on going to see the sub because i still had some thinking to do. plus i was afraid i may hurt my sub had i gone out there last night. that's just how angry i was. but that wasn't what he called himself pissed about. he read my thread to lyndon and went berzerk. acting all upset that i invited lyndon to goldie's party this weekend. i didn't mention his scheduled date today with "little miss whoever" to go see r. kelly, but he just kept talking about how bogus i am because i was making these plans on the 13th (around the same time he was making his plans to see r). so i eventually let him know he showed me everything and he just stopped. wanted to know what i saw and asked for proof. i mentioned one word and he looked like he wanted to cry. he just started apologizing all over again.
i still don't know how i feel about all of this. i wasn't all too sure about having lyndon come to goldie's party, but now i think i should. it would serve him right. we all know i'm not about to do the tit for tat game. i'd rather leave than play games. so i'm teetering on the fence trying to decide whether i should continue. i'm trying not to base my decision off past experience, but i'd be stupid not to.
so now i sit, contemplating...
