I literally refuse to be insecure

My ex of 7 years cheated on me, had a full blown affair with his boss during one of the most difficult times in my life instead of being there for me, had sex in my home, in my bed, shattered my world. But I refuse to let THAT happening make me an insecure wreck about other relationships. Shit would just make me paranoid. I am dating someone who's baby momma.. well.

Man. She gloats about screwing other women's men. She THRIVES off the jealousy, it's a fucked up thing she does. She goes and stays at this guys house with him and his girlfriend and sleeps with him and gets off to the fact that the girlfriend just loses her mind. She told me, to my face, "I'll fuck anyone's man. I don't care who it is." And I scoffed and said "if you can fuck mine, you can have him right back."

Like y'all she has a sick problem but it's not my problem so whatever.

And I meant that shit. If this point, if a man cheats on me, TAKE HIM. KEEP HIM. He aint worth keeping so DO IT if you can. The sooner you try the sooner I know if I need to move along now so CHOP CHOP get to it, try to screw him already. Let me know!

She doesn't like that, so she does this thing when she's over visiting their daughter (dad doesn't want the child at her.. house.. where she stays and crazy shit goes down) where she's like "hey do you wanna come share a cigarette with me." To my boyfriend, which means they go out on the balcony alone because I don't smoke, and she'll look at me with this LOOK you know? waiting for a reaction and I'm just like "see y'all in a few." Literally don't give it two thoughts.

When I don't react, she starts getting an attitude. It's so weird yall. God it's so weird

And no, not one time has my boyfriend even made me slightly think he wants his baby momma back. They had a teen pregnancy and haven't been together in years. I just don't get her at all and don't get why she pokes and prods trying to make me jealous and gets shitty when I don't react at all. Weird as hell
