thank you very much in your response and taking the time to making points. it's greatly appreciated.
the part where you state that No, you hate them and essentially vilify them. is what he's been doing, though you've stated it's manipulation, is just a lie? pretty much everything was a lie?
yes on the communication. I've read BPDs do have more difficulty with that I guess. though many do have difficulties expressing themselves. including myself.

yes on the ... my dysfunction ... i thought, at the time, that was the best ... way to tell him. kinda letting him know, it's hard for me too. Even told him why not get together with the girl friend of his he's been talking with lately to help him get over me (come to find out other things, i won't get into that), it seemed ... appropriate and "logical" at the time. you can imagine how many times, including to the day before, where actually seemed like he was set that no matter what i said I was leaving him. how it'll take a long time and doesn't want to let me go, etc ... i don't know if i really loved him, i thought perhaps i did, sometimes it was stronger then other times in that thought. i had difficulties telling him and what he always wanted to hear. he cried the first time i said it to his face. i know that i was ... indeed very consumed with/by him. he did make me feel ... special and there were things i loved. so yes, i was hurt to having to end it but knew that was the best thing ... too many times.
He wanted me to promise him to never leave him and what it'll do if i did, etc ... he forced the ... leaving by his action of physical attack to ensure it this time.
stubborn yes, some friends that know him said, he's not like that (physical attack as well as doesn't apologize) and another said he's just way to laid back, meaning he shrugs everything off as no big deal.
And perhaps justifying i pushed him to that ... point. i'm the first to admit i yelled, screamed, horrible name calling, punched his butt and slapping ... due to our ... lack of communication and seeing eye-to-eye (lack there of).
what i don't get it, how far does one need to go before getting into treatment and counseling?
Are you in any? what was the ... breaking point ... that'll lead one to ... help get themselves to recovery?
i'd like to also ask how the ... cycle of life in relationships typically go?
i'd think that anyone that could be like a "crutch" to someone suffering from BPD/PD would move onto that next person. how long the duration of the relationship lasts are obviously different case by case, person by person, sure ... i've read some are just months, some few years to decades.
but when / how does one go from one to the next? meaning, when does it finally over and they'll stop trying to "manipulate" the prior person and actually "move-on"? how long does it take? Suppose that's also dependent on some variables.
it's not easy trying to understand how someone who goes that far, physical abuse, to not think HOLLY S**T what have I done? I could have killed her. something like that. i can't phantom how IF you actually loved someone as the way he tried to say he was in love with me ... but then some of his actions, such as this, how is that love.
what's it gonna take, for this guy, an actual death? He's been suicidal, i mean pretty bad i was scared and couple of times why i ended up back b/c of these "threats".
This time is completely different. he's attempt in getting something across to me is ... sneaky (can't think of a better word) and he hasn't done the suicidal antics.
i've read it is very difficult for a disordered person to seek help even if they have thoughts about something's wrong and want change ... it's the next steps they struggle in getting to. how or have you taken those steps and what did it take?
