LTR of 2 years broke up with me in May 2018 over text She was cheating on me and etc etc and that’s when I swallowed TRP

Hung out with a 19 year old girl (HB9, tightest pussy I’ve ever felt and a fat Japanese ass, completely submissive) that had a bf of two+ years 3 days in a row, and she began initiating kino like holding hands, always grabbing me etc

We F close on the 3rd day

She ends up breaking up with her bf about two months later, while fucking me as often as she can (up to 6 times in a day)

We begin dating in August and went to Thailand together, but looking at our pics through her phone (mine didn’t work in Thailand) I saw a pic of her and her ex shirtless. So then I viewed her chat history and everyday she was saying I love you and etc to the ex

I called her out on this after we arrived back in japan (I’m American but speak fluent Japanese and she is ethnic Japanese, 5% of our communications are in English). I broke up with her.

We still continued to see each other and fuck our minds out as often as we could.

Then, she got a job at a girls bar/club where Japanese men come to sit next to and talk to cute Japanese girls. She’s regularly stay out all night and come home the next morning.

One night, she said she got plastered and nearly blackout drunk and laid on top of some local Tokyo DJ for an hour and they kissed etc but she doesn’t remember.

Last time we were together we stayed in an apartment style hotel in Tokyo for 4 days, and the 3rd night she wanted to fuck and I said blow me first so she does and then when I go to fuck she backs out. I’m cool with it not gunna beg and just turn over and go to sleep. She’s on her phone for hours and I ask her wtf she’s doing it’s 4 am. She abruptly gets up and showers and starts packing her shit. I shower after her and when I’m in the shower she says bye. I said one time ‘行かないで’ (don’t go) in a firm but calm voice.

So I finish my shower, and go to the room and she is gone along with all of her stuff. I’m like, fuck it at this point I didn’t do anything so I decided to ghost her. 20 minutes later she is blowing up my phone asking me why I didn’t come after her, and she’s spam calling me. I pick up and she says she wants to meet up later. I said ok.

I go skateboarding and then she calls me more, saying she doesn’t want to meet today and what items of mine she should give back to me. I think she’s bipolar or just lacks human empathy, not sure. She constantly suddenly changes completely, even though I’ve been very understanding and forgiving with all the shit she has done. She did all this knowing she’s going to stay with me in America for 2 weeks in March.

I’ve caught her lying to me multiple times, whilst I’ve put in a shit ton of time and effort and money into this girl because well, the pussy is mind blowing. So now it is February 2019, but in January 2019 we bought tickets to visit my hometown in Los Angeles in March 2019.

So we are going to LA together in March, but right now she is being a bitch. I was considering a serious LTR with this chick, but with all these red flags I think I should abort. I want to fuck her some more in America and before we go to America in March, but after that I’m going to drop her.

Should I even allow her to stay with me in America? Right now I’m radio silent and so is she. For about three days. Not sure how to proceed.

TLDR: 19 year old Japanese FWB (I thought LTR material) is exhibiting terrible signs. How to proceed.

Thanks for reading guys.
