First breakup (Vent)

I don't even know where to start this is such a messy situation and it may be a long one my apologies I added chapters to make it slightly more interesting 😂

Intro

I met my partner 4 years ago and she was incredible, she was so loving, understanding and of course being my first relationship this was huge for me, we have lived in 3 houses together over the years, done daily life with little to no issues, I absolutely adored her and it seemed like she loved me.

the downfall

cut to I'd say november last year, she became distant, almost like she wasn't there mentally, all of a sudden our very open relationship seemed closed off, so many random details I never knew (which personally dosent matter to me but it was a very noticable change) she suddenly didn't seem to be the kind understanding girl I always knew,

D DAY

I knew something was up my gut was constantly telling me that something had to be happening to cause someone to suddenly change so one day I decided to go through her google photos and low and behold I find three videos, taken by her of her in a strangers car giving him head and holy did my heart sink, I messaged her straight away to come home and talk to me asap, she reckoned it was a random guy that came onto her while she was walking home, she was very seemingly digusted in herself and she hated what she did with a passion, the following weeks she convinced me to stay (laugh if you want I understand) she was very very insistent on changing and actually showed alot of promise and I was genuinely very convinced, she was hanging around alot more, going to therapy etc etc life was looking up

Post D day

Bro I don't even know how to start this, we had moved into our 3rd house in early February with some friends it was really nice, she loved the environment, she was signing and all was apparently well untill things became very suspicious, she turned weird again and the biggest red flag was one night I woke up and she wasn't in bed or anywhere around the house, I called her multiple times and no awsner, when she got home (in her pajamas?) I told her to be honest with me because I knew deep down what she was doing, she called me paranoid and that she couldn't sleep and wanted to go for a walk, she turned the whole situation onto her instead of my concern,

You guessed it (Day2)

that night I went through her phone while she was passed out and holy. shit. I found a new Instagram account linked to her phone, with a strange account in her dms with no followers, no pfp and dissapearing messages were on and I knew straight away that this was the end of the life I've been living, Incase you didn't know dissapearing messages on Instagram show you the past few hours, there was a man who was talking about doing everything under the sun to her, her talking shit about me, her telling him everything that I was doing and that she was doing, showing him things that I bought her and how sexy they'd look for their night time meetups, air bnbs, meeting while I'm at class,(THIS WAS ALL WITHIN 4 HOURS) I woke her up and made her talk, and she lied, and lied, and lied to my face with the stone cold hollow face she gets when she's in the wrong, and I caught her every time she lied, she then told me to get fucked and left,in her pajamas with just her wallet and phone, all that I know I'd that she did infact keep contact with the guy even know she told everyone, including our therapist that she didn't, I or anyone else haven't heard anything from her for well over 48 hours, the last glimpse I had was her an hours away at what I assume is this guy's house (he would've picked her up) She has nothing, no clothes, no charger, no toothbrush,no medications and to be honest I'm deeply worried about her, the man was dangerous and unruly according to the messages they had.

And here I am, 21 years old lonely and lost, I have no one, I have zero closure, I know nothing about this situation and I doubt I ever will, rent is now unaffordable in the house I just signed a years lease to, close to a grand in dept with bond money she owed me, everything, my entire life came crashing down and Ill never know why
