Basically a girl starts messaging me. Asking if I left her ex (my gf's ex) a voicemail (No I didn't) I message her back and decided to tell my gf (who I've been in an LTR with recently we said we were gonna have a bit more space) I send her the conversation and she starts going crazy saying she felt betrayed by my messages I sent, where I called her crazy which was a joke and my GF said that I should have come up with a response with her rather then put her down. I personally don't feel there is anything wrong with what I said.
I know I get a bit paranoid half way through but that was just because of the timings. But I want an unbiased opinion. Am I missing something or should she be going crazy at me saying she doesn't want to talk to me ever again

Here's the convo names changed. I'm RO, GT is with J and my ltr is S. You will probably understand it once you read it. Sorry it's long


GT
Hi
This is random I no. You left a voicemail on my ex boyfriends phone J. I need to no the reason behind this if he had been talking with S ?
Monday
GT
Ps I know you probably wouldn't want to cause any issues but I think I deserve to know if there was a reason behind it
RO
What?
Sorry im confused
also sorry about late response
GT
Maybe I have the wrong person
Sorry
GT
Are you S ex ?
RO
Yeah
RO
Well we are kind if still seeing each other why?
RO
what do you wanna know? i wont say anything
GT
Ah okay , probably shouldn't be getting involved in this. She sent a text to my ex boyfriend at the time saying sorry that her ex had left a voicemail on his phone. It was out of the blue and I wanted to no the reason behind choosing him etc. if they had been in contact as it has messed a lot of things up and I still don't no what happened.
You don't need to reply as I no this is random because you don't no me , but I'm in a awkward position to no the truth.
GT
If it was you then I wanted to know if there was something you found as I feel like maybe I'm being lied to
RO
i never left any voicemail
back in august right?
GT
Yeah
RO
i never spoke to him as far as im aware their relationship ended because she cheated
its funny you sent me that message the same day we broke up
GT
this is so confusing then.
RO
me and her literally said we're gonna have a break the same day you sent me the first message
when did you two break up?
GT
Oh right , well im only talking about August as I'm pretty certain it's nothing to do with lately . We're still seeing each other I'm just trying to clear up what happened that day in August. I'm sure it was just someone playing a prank then
RO
Oh well I don't know
But do you think they have been talking to each other? I know S deletes her facebook Messages
GT
No I don't recon they do at all , but I wanted to check whether it was you who sent the voicemail cause there might of been something I needed to no
I'm pretty certain they haven't spoke for years now
RO
Yeah thats what I thought and no I never left a voicemail I don't have his number. Did you ever actually here the voicemail?
*hear
GT
Yeah it was just random shouting,didn't say anything important but didn't understand why she text and said he might be contacted.
Hope this doesn't cause any problems with you two as in certain they don't speak.
I shouldn't of really got in contact should I lol
RO
Best thing to do is just block her she's a bit crazy
GT
It's cool I don't recon she will ever need to be in contact with me
Thanks for responding though
RO
No problem
RO
also if S ever asks id appreciate if you just said nothing
GT
No worries ,Same I've just deleted all of this cause I wanna forget it all so if J for some reason gets in contact you should prob delete it too

Whole thing is sketchy. She cheated on this guy, deletes her fb messages, asks for a break and then shit like this. Don't know what's going on but find a new girl. You're probably being or were being cheated on. Either way it's too much.

She defo didn't cheat on me but she cheated on her ex in the past. Another thing is her flat mates dislike me and it has an impact.

If she cheated in the past and weird shit with an ex pops up, odds are she was up to something. Anyway, the situation doesnt make sense because she is lying to you somewhere in all of this.

Her ex is miles away so I know they never met up but your right she has to be lying somewhere I think shes more likely to be lying about her feelings in the relationship and looking for a way out.
