Apologies for the text wall.
GF and I have been going out for 7-8 months. First LT relationship, her second. I helped her get over her ex-cheating on her, using her for sex and so on, and we fell together. She confessed her feelings first. We went out, had amazing times and things were going great aside from the odd argument.
Then, just yesterday... I colossally screwed up.
Due to her having pain down there, lack of opportunities due to neither of us having our own place (we met as her being 15, me 17. Now 16/18) and so on, we never really had sex across six months. Did other stuff, but after my birthday she took my virginity and we had sex successfully for the first time. She's been amazing, which makes me all the more guilty about what I did.
I've been suffering from masturbation/porn addiction (mostly the former) for years and been actively trying to go clean for over a year unsuccessfully. My sex drive feels on overdrive a lot of the time, others completely normal. She stayed over from Saturday night, all through Sunday and Monday morning. We were able to have sex Saturday night, but did not on Sunday. I was completely content to cuddle, watch The Walking Dead and movies and have the odd make out.
It reaches Monday morning, and due to the costs of getting to mine (we live around 1.5-2 hours apart. Have to get 2 buses and one Metro to stay over) we would be unable to have a house/room to ourselves for several weeks if not more, and I wanted to make the most of the time we had and have sex once more before we had to go. She said she did not feel like it, and for some reason, something flipped in me. I felt zero desire anymore. No urges to hug her, kiss her, anything. We barely talked in the house getting ready, on the bus or at the metro station. She tried to take my hand walking to the bus stop and I refused it. I did not say goodbye properly or that I love her when we were at the metro station. Afterwards, I felt sick.
A day goes by and she texts me this morning telling me I shocked her like I never have before and she wants a break. I'm stunned. We have had rough patches in the past but always talked them through and always stuck by each other, and overcame them in time. We call, talk and I agree to give her the break she needs. I feel so damn awful. I let my selfish wants for a bit of sex come between us, I've never treated her like that before and to be honest I cannot believe I even behaved like that. I've tried to be better for her and not be like her cheating ex (I've never cheated and do not intend to). But I failed her yesterday. We've had some amazing moments together, but I clearly see I need to do some self-reflection and development. I am getting help for my addiction, and I have seen improvements, but it is a long road. She promised me not long ago she'd always stay with me and not abandon me to fight it alone because she loves me and stuff, but I do not know if I've lost her now.
