cell issues

so for the past bit, ever since i changed my cell number to a local ottawa number, i've been receiving text messages for someone named sarah. now, i'm not well-versed in how texting works so i didn't (and still, largely don't) know how to contact the person and let them know that i'm not the person they're trying to contact.

i've tried replying to the texts i've received but they're coming from windows live messenger and therefore i'm not sending them directly to the person but to their email account. the people i have been able to contact, as well, have not responded so i'm not really sure what's going on.

what i've been able to gleam, without really digging too much (cause i could just forward all the messages to my email account...) is that the person's name is sarah and that she used to date a guy but they recently split up (his last email to her had the subject line: don't be a child). the ex has some sort of relationship now with lyndsey who just happens to be sarah's best friend. sarah told lyndsey to have relations with the ex while at the airport (i think she went to africa - many of the text messages are titled re: africa) - btw, relations is my word... the ex uses a less sensitive word...

the ex uses the word 'whack' in sentences like the following... "i most likey wont even see her anyway, but if she or i want see each other we should not have to ask your permission or some whack thing like that..."

another text message (that i didn't read) was titled 'your wife...' which adds to the mystery.

i'll post more about this person when i can (i don't have my cell on my at the moment...).

btw... the ex (who doesn't list his name in the email...) signs off on with 'laters'
