Is My Fiance still attracted to me?

I don’t know if I’m being dramatic and am over thinking this whole thing, but I have a hunch that he isn’t really into this relationship the way that he used to be. We have recently moved in together, share two dogs, are full time college students, and work on our spare time. Quality time is sparse, and few and far in between. The time we spend at home is used for picking up chores, caring for our dogs and maybe an episode of our favorite show before one of us falls asleep mid way. On our days with a larger gap, my fiance enjoys playing with his friends on Cod, and most days I chill and watch my own tv shows while he’s busy on that. But recently I noticed that if I make any effort towards like slipping into lingerie and lightly prepping our room with good lighting a candle and some solo prep, he usually isn’t interested and will either lightly complement me and move to his PC gaming set up or something like his phone of Tik Tok videos or football stats. I guess I’m taking it hard, because the rejection after some effort sucks. Tonight was another failed attempt, where I ended up changing out of my outfit, blowing out the candle and shutting off the lights with a frown. Am I overreacting here? Is there something I am missing and can be doing to help make him want to spend his free time with me, and less on his video games. I need some help here, because he is a phenomenal partner and I don’t want to easily just up and leave this relationship. Our communication is usually really good, but I don’t even know how to bring this up without placing blame on him. Any advice would be greatly appreciated!
