Yep, not used much by me.  I have 4 of them.

Dear Diary,

Was with her for 2 years. I loved her big time (so no ragging on me guys). I messed up the last few months and pushed her away. I was going through some stressful bullshit and ended up letting it out on her and she took it in silence. She finally had enough and cut all ties literally over-night (with the support of her family/friends). I felt terrible, apologized, took ownership over what I did immediately and continued to whenever she'd take my call. She wouldn't hear it anymore. She blamed me for everything and went from being sweet and loving to mean and nasty post-breakup and is with a new guy almost no time after the breakup (found that last part out today from a friend who saw her post pics of the 2 of them on instagram with hearts). I feel sick to my stomach. Anyway, up until today, I wanted her back (a 2nd chance to make it right). Now I'm just pissed off. I gave so much to this girl and she went from being so devoted and loving to telling me I'm a horrible person and other cruel shit and is "in love" with someone new in almost no time. The dude is sleeping in the place we found together only last year. This has messed me up big time. Serious post.

You see, up until today I was on my best Goddamn behavior with her. Been cool, apologetic, even paid her back some money (through e-transfer) she lent me when we dated. What put me over the edge is feeling bad about how much I hurt her and that's why I let her talk down to me AFTER the breakup, because I felt I deserved it, but now knowing she's already in love with someone new makes me not want to be so nice anymore. I really do want to fuck up her new relationship in an underhanded way, or just plain hurt her. I actually loved this girl and all the time I spent with her feels meaningless now seeing how she treated me after she left me and how she jumped into a new relationship pretty much right away. I feel like a fucking fool for being so nice to her all the while she's sucking some other guys cock and he's sleeping in the same bed we found together a few months ago. This does not sit well with me and do not want to go away quietly. Obviously, I don't want to do anything to get my ass arrested, but I do want to go out swinging where it hurts her the most.

I don't know man. I don't think hate is what she has for me now. I thought so for awhile, but it seems like a lack of respect and common courteousy/decency and she looks down on me like I'm now beneath her. I fucking RULED her when we were together. I am not proud of that, but I dominated her until the day she left me. I have since been kind, apologetic, mature and a standup guy and she has become vicious, mean-spirited and hurtful. What has put me over the edge is finding out today that she's with someone new so soon after and publicly announcing her love for him online. It's a slap in the face and I want to knock her off her Goddamn pedestal that I put her on.

I was so pissed off today from hearing that she's already in love with someone new that when some dude cut me off while I was driving, I stopped my car, got out of it and walked up to his window and told him to step outside while I fuck him up. I've never been this fucking enraged in my life. The dude told me to calm down. I told him to fucking never cut anybody off again and I stood there blocking him from driving off until he told me he wouldn't cut anybody off again. I was ready to fucking kick his ass. Even if I couldn't, I was prepared to find out. Not trying to brag, but just being honest with how pissed off I was today.
