Second guessing my engagement…help ):

Hi everyone 25F 23M I write this feeling very sad and confused and just hopeless…me and my partner have been together for almost 5 years (5 years in march). We live together and we obviously have good times and bad times and always have…but we are at the point in our relationship where we are in the roommate stage it feels like. We are getting married this year 2025, but I catch myself second guessing if i want this for the rest of my life. I don’t want to feel like roommates forever..and i just feel so tired of our life together. Our life is so repetitive and the same thing over and over and i just feel so bored. I actually enjoy being at work most of the time as it’s good time apart plus gives me purpose during the day…but idk. I also have been finding myself wanting validation from other places. A lot of guys flirt with me at work in subtle ways or like tease me or banter back and forth and i find myself excited about it. i find myself wanting to look pretty at work so that i can get attention. My partner gives me attention but im wondering if it’s just not enough? He is a really good guy and we have been through so much together and it makes me want to die thinking about not being with him but then also, a small small part of me would feel relief and feel free but i know that this feeling would be short lived…i used to feel excited that i was going to be getting married but now it just feels like a chore at some times of like something that is just going to happen, not something that’s monumental i guess? idk how to explain it but i am just so confused and am scared about these feelings ):

TLDR: feeling like roommate stage with fiance, confused and unsure of what to do and if this will get better
