My roommates started dating and I am having a hard time adjusting

so, we had all met from work and before that roomie A (F21) and i (F21) were becoming close friends and hanging out a lot outside of work. then our other coworker (roomie B, F22) needed a place the same time we did. so we found a place for the three of us. so we started renting a house back in aug and eight months into the lease they decided to start dating and have been since (abt 7 months). i recently signed on for another year but am beginning to hate living here more and more. they didnt tell me for a month but i started sensing things were off and was getting more and more of a vibe that they were getting closer and i was getting more left out. since then its been really hard for me to get used to living w a couple when i didnt sign up for that. before they started dating we were all friends and a trio who did stuff together a lot. now its just them two and me and roomie A never do things together anymore. i hate seeing them pda in the house and they are always in each others rooms. i had to ask for them to shut their doors if they were gonna be touchy. its gotten better but if they are cooking in the kitchen or watching a movie on the couch (usually being loud and/or too pda for my taste) i hate going outside my room. i know thats definitely a little of a me thing but i really hate feeling like a third wheel in my own house and also feel like i lost roomie A as a close friend. we still have good talks sometimes but we are all busy and they just seem to make time for each other now and even if we all three do hang it just feels awkward for me so ive stopped trying.

looking for advice on dealing with this until my lease ends next august?

TLDR : my roommates started dating seven months ago and i didnt sign up for that. we never hang out as friends anymore and it feels awkward now & they only make time for each other. ive stopped reaching out & they dont either, i’m a third wheel in my own home and hate leaving my room. any advice for dealing with this?
