Hi. Is the ex trying to ruin my life?

i was dating this person for almost 2yrs when i decided it wasn't for me. so i told her it was over. unfortunately this person said she'd fallen for me so was heartbroken. which i was sorry for but these things happen. whilst together she became very friendly with all my family and best friend and was very keen to get to know evry1 tht knows me including Friends. after the break up she constantly txtd and emailed me asking if we could get back 2gthr. when i refused she got very stroppy and startd accusing me of things tht weren't true like cheating and womanising. she'd try 2 get information off people i know so she could try an use it against me. she'd set traps to try and catch me out. bombard me with hurtful txt msg's then a week l8tr txt me askin 2 be friends. this went on for at least six to eight months. iv had know1 to talk to but my best friend who iv known all my life and thght i cud trust. my own mother seems to be best friends with her and take her side trying to get us back 2gthr all the time. anyway i changed my phone numbr an things wer quiet for a few months. but those few months it was quiet she was pestering my best m8 to go round hers and shag her the tramp. and like a prat he's been shadily knob in it. and now shes trying 2 get a relationship going with him. now she's doing things like asking my mother to babysit her kids (who are no relation by the way) whilst she's out dating my closest friend. wt a knobber. and wot hurts is tht my own mothr who says she loves me very much is running round doing all these favors for her. ****. this person if u can call it one gives evry1 the impression tht shes a very nice person with a gud heart. which she was wen i 1st met her. but it seems nw tht she is tr yin 2 take all my close family and friends away and leave me isolated and on my own all because i didn't want a relationship. most of the time i choose to ignore it and nt let it get 2 me an jst get on with my life. but out of the blue sometimes pops up this deep bitterness leaving me feeling angry like i want revenge. as i wont stoop tht low i feel there all getting away with hurting me even my own mothr. this is still goin on 2day iv no 2 talk 2 nw the bessie has stabbed off. its like thr all under her spell and making out iv got the problem. any ideas on how to resolve this would be appreciated and feel free to comment ur thoughts. Thankyou. soldier on,oasis.
