u/Neither-Cellist-458

Firstly thanks for all the advices. There were a vast range of opinions,and i was not sure which ones to consider and which ones to not.i just went with what felt right for me.

I took some time to calm down and yesterday night I confronted my boyfriend. And oml I cant believe I spent so much effort and love into this person who doesn't even give two fucks about me.

He started justifying his actions and told me he considers her a 'sister' then I told him I had seen the Polaroids too that's when he lost his voice.i just cried and asked him again and again why would he do that to me and he just kept apologising and telling me it wont happen anymore. But ik better than that, i told him I dont wanna see him for some time.

i was thinking to confront my sister but her call came first. And ofc like always instead of showing any sense of guilt she proudly owned upto it as if it was some sorta medal.

this has happened more than enough times. I have gotten angry over things like this bcs of her multiple times. But I am done now.i love her as my sister but I can never love her as a person.

I told her she can do whatever she wants but to stay away from me and that I wont be associating with her anymore.

She tried ragebaiting me again but I directly blocked her. I cant deal with her anymore.

As for my boyfriend I am not sure what to do I put so much love and effort into him. He is the only person that I used to feel safe with and now that's gone too.

For context me and my bf have been dating for a whole year now.

We have had a great relationship and no problems throughout. I would have never expected anything bad to come along let alone cheating.

My sis and I are close but she is highly problematic she always copies me and flirts with people I like.

I always knew she was a huge pick me which is why I tried my best to not let my bf met her, and idk why the fuck did I let them even meet.

My sis was being all over him during their first meet but he wasn't paying heed to her which made me happy and I thought I wouldn't need to take any precautions in the future.

Me and my sis share the same birthday month. I had went to my bf's apartment to chill. he had to go out in an emergency, he told me I could stay there and rest.

I was bored so I went around snooping when I found a huge box gift wrapped with happy birthday written on it.

I got very excited because my birthday is just in 10 days so I thought he had got the gift early for me. I couldn't help myself but to know what was in it. When I opened the box my heart dropped.

It wasn't me but my bf and my sis together with Polaroids of them hugging and kissing with makeup and other goods and a letter about how much he loves her and how she is the only one he wants🙂💔

when I had told him I loved handmade gifts he just shrugged it off and said it takes too much work.

I literally lost my shit I called my bf a thousand times but he didnt pick up. I am currently at my home now with 3 missed calls from him and idk what to do. I fucking hate my sister so much for this she has always stolen away everything from me that I have ever wanted.

I dont have anyone to ask advice for pls help
