Scary Thoughts 😩 ...

I wanna know... Have any of You ladies ever caught yourself thinking about someone you KNOW you Shouldn't while you're in a relationship? Like an Ex Boyfriend, Fling, One Night Stands, Bestfriends or whatever it may be. For this past week I've been catching myself smiling and thinking about two different people I once had in my life. My Ex Boyfriend and this Friend Guy (we were both into each other but My BF and I were on & off so we knew it couldn't lead to anything. Nothing Sexual ever happened, only kisses. Well maybe a dry hump session but that's all). I don't know why they've suddenly been coming to my mind. I don't want to be nor get with them. Although I can admit I do miss the Friend Guy... I Feel Guilty. I Feel Wrong. IT feels Guilty! IT feels wrong... Is this Mentally Cheating? Even though I don't want to be with them nor do anything sexual? Omg! And they come at the weirdest times too. For example, I was making a PB&J Sandwich and there I was, Smiling. Smiling thinking bout the Friend Guy! Like WTH! And I can't tell My Boyfriend about these thoughts neither cause I'm sure he'll blowup on me and think I'm actually doing things with them or that I want to and in All Honesty, I DON'T! I need help Ladies. What do I Do????! How do I Make Them Go Away? Is this Mentally Cheating? 😩
