Being blatant honest WITH LTR when I'm low/depressed?

M27 here. So, I've never had much success with girls, and in my first ltr at 21 I got cheated. This made me feel much much pain, it was one of the worst moments of my life.

Several years go by, and I find out r/seduction, and start getting good results with girls, and also started expanded friendships. One of the things that struck me the most was about the concept of being honest and vulnerable. This way I would be truthful to myself and would be willing to piss or not be liked by people. The book Models, of Mark Mason helped with this.

After a few months of good results, I found a nice girl, and she had everything I hoped for. I committed to my philosophy, and some times I even cried with her because of my overall stress, as I was finishing college, had problems at work and several other stuff. She was always understanding, and after our talks I would always feel a lot better, since I had someone to talk to. I was happy to be 100% real, even with my shortcomings.

At this stage, I still had high self steem from the results I got with girls, and still bounded a lot with my friends.. After 4 months, I mostly see my GF, and my overall happiness and self steem is low. I think this is happening because she's the only source of validation I have right now, since I stopped seeing friends, stopped working hard in my career, etc. I'm really low, I'm were fighting for ridiculous stuff, mostly because I can't control my shit anymore. Thing that is bothering me the most(which I didn't tell her because would lower my SMV a lot) is when she hang out with friends and I can't go (because of work or other stuff).. I'm afraid she may cheat me. In the beginning of the LTR I didn't care at all, because I was also meeting friends and whatever, I was high smv and I knew it that if she cheated or whatever, I was completly fine as I could get other girls easily.

So, from a purple pill perspective, should I tell her I'm jealous or should I just stop seeing her so much and work on myself? Should I make her commit to not going with friends alone and other beta shit? I don't want to put bullshit stuff into the LTR, and still want to be myself. But the time I told my old LTR that I was jealous, I think she felt how low SMV I was and used this to cheat me. I'm afraid this will happen too, but maybe this girl is special and will help me?
