broken up (again)

[kt959]

i hope you can shed some light on my situation. i became involved with a man that i've known for a few years earlier this year. he was still living with his girlfriend, with whom he has children. i knew of her through our respective children. i was in a relationship at the time we struck up a friendship, note - he actively pursued me and i genuinely believed it was a friendship. as time progressed, it became physical, and i was told it was over between them. i ended my relationship as i'd never cheated before and wanted to give this new relationship an honest go. the cycle then began. he couldn't bear to move out and leave his children, so we broke up pretty much every three weeks from may to present. i tried to be patient with him as i'm sympathetic to divorce as i've been through one myself and the separation, despite how acrimonious, can be terrible. he finally left, or was made to leave by her, a few months ago. unfortunately he decided he couldn't integrate our children nor have us 'come out' as he was afraid she wouldn't allow him access to his children. i carried on being patient and he carried on seeing me, telling me he loves me, etc. this last break up has had more reasons: he can't juggle work and seeing his children (he sees them daily for hours) and 'him' time and a relationship. apparently the something that had to give is me. i've taken it quite hard as we were best friends as well as in a relationship. my friends have told me to run as fast as i can because he's so dysfunctional and will carry on being on/off forever. it's hard to try and move on as i see either him or her at school every day or in the town. i've never cheated nor been the other woman and i accept my part in what happened. i suppose i just can't understand how a man can be so hot and cold. has anyone else experienced this or have any words of wisdom? i keep hoping he will get in touch (i refuse to contact him as this is his decision; in the past, it's been me who asks for us to meet and we make up and carry on. this time i am too hurt to do so) and want to speak or see me. we have amazing times when we are together - wonderful laughter, great conversations, he's amazing with my child, the sex was fantastic. . . i can't understand why he'd end it? thank you so much for reading my post.
