Hey if it can help, it's the other way around for me.
I'm the one who's gone for 4 months in South East Asia and am now in an LDR with my LTR. She cried a lot at the airport when I had to go.
She knows I'm a huge player, during all our relationship I even took numbers right in front of her and she openly told me that it's when she stumbled at me at the tram station flirting with another girl that she knew she was in love with me.
She's a RP woman, I was her first one, she comes from a very healthy background, she's frugal, non materialistic, love nature, like the simple things in life, an amazing cook, super fit (national level ballet dancer for 13 years, martial art practitioner for 3 years), and our sex life is amazing and she's crazy in love with me and dropped all the toxic people in her life and is the one who's willing to cut all ties with her friends, family to move accross the country with me and it's not the other way around. She has healthy friends she does sport and cook with and they're not heavy party type of girls.
I found a girl who had the quality to be my LTR whereas I used to be a player, so we skype everyday for hours, we both know our agendas, and depiste the 5 hours difference, every morning when I wake up I've got 3 to 4 new videos of her doing sexy things for me on cam and telling how much she loves me. It turns out I can make her cum with only the dirty stuff I write about the thing I'd like to do to her.
Everynight she talk my self to sleep over skype and she will join me in September (She will work in a factory killing ducks for 2 months to finance her trip) and we will travel south east asia together for a whole month.
I've never cheat on anyone and never plan to, she knows she's just a bonus in my life and I realize that with or without her, my life wouldn't be different because I've achieved happiness on my own. A core concept as a RP man is that girls doesn't affect our happiness level so we can't be needy because we're enough on our own.
I know that if one day our relationship has to end I'll just soft next her, cut contact and move on with my life, because I know girls are abundant and I can just easily go back to plates or find someone else.
So I've chosen to put my trust on the line and I don't care of the outcome, because so far our relationship was perfect and I won't be the one to be toxic. I just know that if one day it has to end because I'm not respected I will remain stoic and just move on and cut her out of my life.
As a RP man you live the life you chose, you're the one deciding of your core morals and values. People here will tell you to line up the plates and demote your Gf without letting her know as a preemptive measure. But If you state your boundaries first and that the frame you set for your relationship is strong she knows that there is no second chance because you're a respectable man.
Next time, try to travel together and for now try to have a fucking good communication level with as much transparancy as you can. If so far she was good to you, there's no need to have any insecurities like you're having right now. Try to dissociate your emotional state outcome from your girlfriend and girls, read more on stoicism. Even in a relationship or a long distance relationship you canno't do anything but keep seeking the best version of yourself by improving your smv, dread game in the context of your Ltr is when things already went south don't put yourself in this situation in the first place.
So good luck and ask her to send you sexy videos and pics of her everyday while she's gone.
I wish you the best
