Hello! So me 18F and my boyfriend 19M have been together for about 3 years. We have known each other since we were 11 and friends since we were 13. We started dating when we were 15. I had never really had much luck with boys and had some pretty nasty boyfriends before him but he was always there for me and when I started going out with him I thought he was sweet and sensitive.

At first things were so good and I was basically the happiest I had ever been but after about 5 months, I tore my acl and needed surgery as I couldn't walk and I get that it must have been hard for him because I was pretty down because, as a fairly active person it was really hard for me to feel like I was reliant on other people. It was about this sort of time that a switch absolutely flipped in him and he completely changed and after that he just would be impatient, said I was draining him just by texting him, go to bed after an argument without even saying goodnight when he knew I was crying my eyes out.

I genuinely couldn't eat or sleep I was so in love with this man it literally tore me apart. We had some really important exams and I was so so so so sad I could barely revise. Over the summer things got worse and whilst I was on holiday with my family he was the worst he's ever been, he kept asking me for inappropriate pictures which I thought was weird because even though we had a very good sex life he never really asked for nudes or anything. He was quite demanding and the rest of the time he was absolutely horrible to me, one of the days I couldn't leave my room I was just crying all day I had to pretend I had food poisoning but I was just sat in bed crying so much.

Anyway fast forwards to October things start to improve and I'm like omg he's being nice to me wow. We've always been pretty open about phones and stuff and although I'd caught him liking instagram models photos and stuff it was never really anything serious, we have the same phone password and each others logins to stuff just for convenience because we are around each other so much we kind of just use our phones interchangeably.

That being said, there was one very very important rule in our relationship. He asked me before we were together whether I felt comfortable with him watching porn and to be honest I said I'd not really considered it before but probably not no. He said okay and said he wouldn't watch it. I didn't think of it again until summer when I started getting so worried about what he was doing behind my back, I asked him so many times are you watching porn and I still have the image in my head of how he'd tuck my hair behind my ear and kiss me on my forehead and promise me he'd never do that. Needless to say it was October when I found it on his phone, he hadn't lied a lot in our relationship so after some convincing I believed him when he said he didn't do it. December. I found it again. I tried to break up with him but he begged and told me he has an addiction and I stayed.

After that, he's proved to me in every single way that he's not doing it anymore and that he's changed, in fact he's gone above and beyond to be perfect when i've been worried or anxious to trust him. He has been everything I had ever wanted from the beginning, I'm talking love letters and flowers and surprises and dates and that sort of stuff.

Anyway all was well until about a week and a half ago. Everything changed again. He has been absolutely foul. I don't even know how to describe it, just exactly like he was being before, swearing at me constantly, he's completely stopped complimenting me, saying I'm draining him, completely disregarding my feelings in every situation, barely talking to me, constantly on his phone. I literally don't know what the hell has happened. I love him so much and I've tried to say what's happened this isn't like you you seem off again blah blah blah. HE DOES NOT LISTEN OR CARE. I feel so genuinely exhausted from crying so much recently, I don't know what to do would I be a horrible person for leaving idk if I can do it
