[Defeat]

Seems a stupidity, but im struggling so much with my gf, she lives on another city ( 150 km away from mine ), and every night she goes partying, the Next morning she tells me she has been talking/dancing and getting invited to drink by other dudes, and i feel someday she wont tell me that because she would have done more that that with those dudes. I know i have to trust her, but, when you have came from 2 relationships in which i found she was with other dudes... Its very difficult ( we are making 2 years of relationship on Sunday ).

Sorry if this seems like a teenager problem, It really Matters for me, keeps me awake every night she goes partying, i barely sleep 2 hours those days, and the normal days barely 4, and im 20... So imagine how i feel phisically and mentally every day

Cut that off. Even up there, she lived in another city and if she was doing that it would've been over a long time ago.

Shes my 1st love and 1st relationship, i know that if we end here, i Will just die inside... I Will start doing nothing and forget about myself

Awh young love. 99.9% of relationships end buddy, she's harming your self-esteem and your mental health, why stay? Lol there'll be better girls, I promise you that.
