my girlfriend(22f) (been together 2 years and 5 months) is becoming distant and our sex life is fading more than what it already was. when we got together things were great. we had started talking when we were 17. she had recently gotten out of a relationship and we met through a mutual friend of ours. i chased her for 3 years on and off because i would keep getting told she wasn’t ready. i ended up living with her for a month due to family issues that i had after graduation. our bond grew and then i left and moved back into my family’s house. we ended up growing apart for a bit. meanwhile i worked like a normal and spent my free time drinking and talking to other women. i slept with a few women just to pass time. time passes and we start conversing after i found her on a dating app and jokingly i messaged her about seeing her and then we rekindled. i ended up going to see her and we started actually talking talking. in the beginning things were great. she traveled with me when i had to go out of town for my job being that she didn’t have one. at the time i lived with my grandparents after i got kicked out of my parents house. we spent tons of time together. i would go to her grandmas where she stayed and would stay until late hours of the night. sometimes when her grandfather wasn’t home during the week i would stay with her. her grandmother ended up asking me if i wanted to live there with her and i agreed because it was a hell if a deal in my eyes. well i ended up getting tired of her grandmother. i respected her but didnt favor her. i ended up moving out and back to my grandparents. it broke my girlfriends heart but i just couldn’t take it anymore. later we lived with her cousin and family. ( we drank most of the time we were together in the very beginning when she stayed with her father) i had an alcohol problem and used it as a crutch to deal with everything i had going on with my family. i would almost rely on alcohol. it got bad and she didn’t like it. we would argue bad , i was a bad drunk. so i ended up quitting/ slowing down. we moved into her dads girlfriends an i would drink on occasion and then eventually quit altogether. (random insert- she has had one job our whole relationship ship that lasted for a month due to issues that she has/ had)at this time my uncle was in bad health and had a stroke and was disabled. my grandpa offered us a place to stay at for free, all i had to do was help my uncle and pay half of utilities. she had a childhood friend she would hangout with off and on our whole relationship. her friend had and still had a boyfriend. we ended up being friends i guess you could say. we hung out a few times while my gf hung out with her friend. i went to him for advice about my relationship. my gf has done some questionable things. she has slept with someone that was 40 while she was 18. long story short i ended up on a dating app swiping through women because i was un happy and was encouraged by my gf’s friend and bf. my gf ended up finding out. i realize i should have never been on there. we argued after she found out and she ended up staying. i deleted the app and canceled the subscription that i very stupidly purchased and deleted my account. her trust for me wasn’t there after that, understandably. now it’s pretty much nothing but arguing. our sex life has diminished to its lowest. i hound her all the time about finding a job that way we can move forward in life. i work 40 hrs a week at a utility company. i have paid the bills since we moved into the place we live at now. opinions? she is always dogging me about changing my ways. thoughts? advice?
