heartbreak is just another fact of life that we have all experienced at one point or another. believe me, im coming down off of my own right now too, i swear its not the time of the month, its the time of the year. 1 year, 2 months (yesterday) or it would have been.
put things short, i got a text message from one of her co-workers telling me to get her on a leash, that she was showing explicit areas of herself to him, and asking to f*** him and that she wanted to s*** him and all of that. it wasn't pretty when i found out, i confronted her on friday morning about it, and of course, she denied it, until about lunch, then she started coming out with it, but after school... it was chaos. I had a $400 package from ups sitting on my front porch full of motox gear that got there at 11:00 in the morning, and school got out at 2, so origional plan was to get there asap and secure the box inside so nothing would happen, well she wouldnt let that happen. she stretched the crap outta my jacket telling me not to go (and at this point i dont even want her in my life) so i called her mom, she didnt help me out, called her step-dad, he didnt have the car, called my dad, he was working (but suggested to me to call the cops), so i executed the final option in 4 swift clicks on my phone. i really do hate that it had to come to that, but that was the 10th and FIANL time i was going to let her go behind my back and do something AGAIN. she confuses her wants with her needs, and only being able to see her for roughly 30min a day was not satisifying enough for her, so she hit on every guy in every one of her classes when ever i wasn't around. worst of all, about 3 weeks ago, i found out that she made out with another guy in the first week of us dating. some women can just be so unbelieveable....some of the stuff they pull, and get away with it, just cause they can pull the gender card.
im coming from the same boat as you too (my first time and all), but dude, **** happens, its one of the hard facts about life.
my advice to you would be the same advice my friend ivan and my friend ariel gave me. Occupy yourself, find a new hobby, be constructive with your newfound free time, try and get back into some of your old favorites that you had before her (like me it was bmx (hence the email) or dirbikes), just have fun with it. I realize that you are going thru some stressful times too, this thanksgiving week is like a godsend to me, gives me a decent excuse to laze around the house being a vegatable and start doing research for what im doing after HS, what courses im going to take, etc.
