I (24F) want to break up with my (23M) bf.

I don’t even really know where to start, me and my bf have been really close friends for around 4 years. We became part of the same friend group and would always be around each other just based off of mutual friends. He’s seen me with other men and the same for me with him. We never really had anything more than that and it was never a thought for me. Flash forward to a year ago, we both ended up living in the same city with my 2 best friends and we would hang out every now and then. One night we both got really drunk and hooked up, and i immediately regretted it because i didn’t feel any way towards him and i didn’t wanna give him the wrong idea. Months later it happened again and it started happening more frequently but i still wasn’t sure how i felt. I started to develop some feelings for him and i could tell he liked me and within a month of us frequently hooking up he asked me to be his girlfriend and i said yes. Looking back i should’ve sat with my feelings for longer because i knew i didn’t feel super strongly about him but thought they would get stronger with time. Unfortunately, 2 months into our relationship me and my 2 friends needed a new place to stay due to our leases ending and we decided to move in together to save money and split rent. Because my bf was around all the time we extended that offer to him as well and he accepted. I didn’t think much of it because we were friends for a long time and it didn’t feel like i would just be living with him alone (honestly just stupid decision after another). Now we’re a month into moving in together and i realize i don’t feel the same way about him. He hasn’t done anything wrong to me personally but I’ve noticed traits that i wouldn’t be okay with having in a long term relationship (Bad hygiene, horrible financial decisions, irresponsible, and just overall having no set plans or goals). It’s not that i don’t necessarily like him anymore but those are all turn offs that i didn’t necessarily see considering we just started dating and they didn’t become apparent until after we moved in together and now he’s taken the spot of a child we all have to take care of. I don’t want to sound mean because he is someone i genuinely care about but I’ve realized that I’m not in love with him but i don’t want to hurt him. Now he lives with us and i can’t fathom bringing this up only a month into our lease. I would just like general advice about this. Sorry i was rambling i don’t want to put every single detail in here but i needed to give the general background information.

In short: I don’t see myself being with my bf long term and i want to break up with him but i don’t know how and he lives with me now. Has nothing to do with how he treats me but more of us not being compatible in the way we live our lives.

Please don’t be mean to me, i know i was making dumb decisions but i wanted to make it work with him because of how much i cared about him and our friendship, and i didn’t expect myself to feel like this after just a short period of time.
