confused

how do i tell my fiancé that i feel like he’s not making enough time for me? we both work full time but lately i feel like i only see him right before we go to work and after we get off. our wedding is in 6 months and lately i feel like there is just no time for us.. and i feel selfish for saying it but i feel like it’s all about work anymore, we hardly ever fighting but here lately we’ve been bickering about small things. how do i bring it up or talk to him about it?
