i've only ever broken up once. it was very sad and painful. i had to leave town and stay gone, start a whole new life. the person i'd been with for 8.5 years was GONE FOREVER. in his place was someone i couldn't respect, trust or feel affection for. i was turning mean. i didn't want to be that person. i knew it would end someday, but when i did, i cried off and on for 3 months and refused to date anyone until he understood well and truly that i was gone. jeez. it was just so damned sad. we sorta grew up together.
I try to have good break ups, I'm still friends with some of my ex's. Not to say I haven't had my share of messy ones, though. My last two break ups didn't end well. I didn't technically break up with the last one, but the guy before him, I just told to get the fuck out, leave me alone, and if he ever tried anything with me I'd beat the shit out of him, which he did and I did. They were both pretty abusive relationships, so it's not surprising it didn't go well either way. I usually like it to end well because it's usually someone I care about (hence the dating part) and just doesn't work out as a relationship. It just depends on the relationship and it's surroundings, how you should do it.
Everytime I have ever broken up with someone I've been in a long-term relationship with it has ended with "and don't you ever fucking come to my house or call me again" and storming out or hanging up on them.
I can not take rejection very well, I've been dumped twice. The first time I was DONE with the relationship anyway... so it really didnt' effect me and the second time was REALLY hard. It mostly came out in anger.
I'm always the one getting dumped so I don't know. There's never much confrontation or talking...they just up and leave or drift away. The first time hurt me. I spent a month trying to repair the relationship...y'know...trying to "win her back" or whatever. I finally wised up and realized she was enjoying watching my pain. That was the turning point for me. Now they just come and go on a very infrequent basis. I don't expect much from relationships...it's foolish to depend on someone else for your happiness. If I find a keeper, great. If not...oh well. P.S. This is not a woe-is-me post. Ha Ha.
