I need help to stop me from doing it.
I deleted Facebook a couple of months ago to concentrate on my disabled DS and my DP. I kept getting drawn in to other people's dramas and ended up being a personal babysitter, taxi driver and basic dogsbody to pretty much everyone.
I then got really poorly with severe internal scarring and rheumatoid arthritis. DS also just started a new set of investigations into his own condition and is moving schools. It's really stressful here. So I decided to come off Facebook and focus on DS and DP for a while and get everything sorted. I wrote a status and left it on for 2 days, telling people why but saying if they really needed me id still be around and offering my number out to close friends who didn't have it. Lots of people messaged me swapping numbers, it was all fine and then I deactivated.
The past couple of months have been really stressful, a couple of people have text me and we've met up with the DCs in the park. But mainly I've been focused on everything at home. I thought everything was all fine and lovely.
Until the other night. DP went to work (in a bar) DS went to his dads and I got on with the housework. I left at 11 to pick up DP but the pub was still packed, so DP told me to stop there and have a drink and he'd drive us both back 
he's a sweetheart.
So I stopped for a couple but then DPs ex, who is fine, but a bit clingy, started hassling me a bit, nothing terrible just following me, trying to find out details about our lives, she does this a lot and I'm friendly but vague with her, DP saw this and told me to see if anyone was in the other pub we go in and he'd text me when he was closing so I wouldn't have to deal with her, and he knew I hadn't been out or done anything for myself for ages so he wanted me to have a couple of hours off. So off I went.
In the other pub I saw my friend dave and his girlfriend. I chatted to dave and he introduced me to his new girlfriend and I started talking to her. About 5 minutes later my other friend turned up, one of my closest friends, or so I thought. I waved but she didn't see me so I told dave and he went over to say hi but she turned her back on him. He came back and told me and I said "oh she's probably just pissed" then I got a text off DP saying he was closing and went back to him.
The next morning dave* rings me and says "I know you aren't on Facebook but your friend has just put a status on saying we were in the pub snogging last night! My girlfriend is fuming with your friend, why would she say that?"
I was obviously really confused and text her asking why she'd said that and told her that dave and his girlfriend are annoyed about the obvious lie, plus anyone else who was there would know it was a lie, and asked her what I had done to make her do that?
Anyway dave rang again and said she deleted the status instantly and wrote "not even bothered, you lied about my husband that's why I hate you"
Now I haven't really spoken to anyone properly apart from DP for the past 2 months, when I've met up with people I've only spoken about DS, and I don't really know her husband well, just that he's friends with DP but I don't often talk to him so I wouldn't have anything to say about him anyway :/.
I text her again and asked her what was wrong with her and then she just deleted all her statuses and started putting stuff about not liking people. I don't really know what because I told dave that unless it was a lie about me then I didn't want to know.
I'm really confused about what I could have possibly done? I did delete snapchat the other night because my friend was having a party that I hadn't been invited to anyway (so it can't be that I didn't go) and was sending lots of snapchats at 2am and had woken DS up (I have my phone on loud because DP works late and I worry) but surely deleting an app wouldn't cause someone to act like this would it? I've babysat her child while she was in hospital and I've been with her to all her other child's appointments to push for a diagnosis with her and I've been her personal taxi for the past 2 years. I really don't understand.
So, after feeling like I was actually 13 again for a couple of days and not wanting to tell anyone because it sounded so ridiculously childish, today I have got the rage on and keep reactivating Facebook, writing out really ranty statuses (which I have never done before, I hardly ever posted) and then just cancelling them before they posted and deactivating it again.
It won't help to do this will it? Tell me to just ignore it all and to let it go and slap the rage out of me please?
I'm just really annoyed that she'd tried to break up my relationship by lying because she "hates me" but won't tell me what I've done.
Someone please give me a shake and tell me not to stoop to her level.
