Is he attracted to me

Me and this guy (colleague) spend all day together, we go on breaks together go for lunch, go for long walks after work. He tells me I’m beautiful pretty much every day and I’ve caught him checking me out his not exactly subtle. He remembers every detail about me and knows all my facial expressions and all my quirks like my laugh and what phrases I use a lot. I can feel my face light up when his around and his super attractive. He also told me my personality is the best his come across and he loves spending time with me.
