Relationship Problems

Why is she being so lovey dovey and crap lately? I mean, really, she is so annoying! I was tellin’ my buds the other day and they were like Dude, dump her. She’ll cry for a few days and then it’s all over. And in the end, you seem like the cooler one. Yep, get her, then drop her. It’s my moral for sure.
I like her and all, but like, I can’t stand her.

I said ew, but I shouln’t have. I know I shouldn’t have. She only started sobbing more. She was crying more than girls watching Titanic or Gone with the Breeze or somethin’ like that. So I just walked away. What else was I supposed to do? I didn’t feel guilty after that. Most guys said I would, but I didn’t. I didn’t miss her. I didn’t long to have her in my arms again or no crap like that. Really. I’m not a guy who can’t be sentimental. I’m a guy who hates being sentimental.
