Inappropriate talk....

My bf has non-physically cheated on me before with another woman about a year and a half ago because he was planning to break up with me...and then I saw him playing around with his ex trying to get her in trouble with her current gf in a playful manor. But the crazy thing is he preached to me about 2 weeks before hand that I make guys feel to comfortable with me and make them feel like they can say anything (over Xbox) what I do is let guys speak and as soon and they try to find out about me, I tell them I have a fiancé and a child and I want no parts. I can't get over it because HES TOO FUCKING THIRSTY! He has preached to me time and time again that he has stopped. But sometimes there is pussy (me) right in front of him and he still goes to beat his dick -.-. All guys have a right to masterbate when your pussy isn't available, but damn bro! In right fucking here. He goes to the bathroom in the middle of the night, fresh in the morning, when he gets home from work (sometimes because he just really has to poop; he dosnt use public bathrooms.) We do live with others, but when we are home alone he STILL DOSNT TAKE ADVANTAGE. I even make sure I'm shower fresh! Sometimes I want to beat his face in with a big ass dildo and say "What. The. Fuck. Is. Your. Problem?! Am. I. A. Fucking. Tree?! Am. I being. Punished?! Is. Your. Testicular. Muscle. Broken?! If. Not. Fuck. Me. You. Big. Black. Piece. Of. Shit!!
