I don’t know what to do

I’ve been with my partner 6 months and I love her so much and it grows daily. She says that she loves me too but I’m pretty sure she’s falling out of love with me. It’s the smallest things like the fact that we don’t have intimacy anymore and I’m not just talking sex (we go up to a month without having sex these days) but other intimate moments like cuddling and kissing. She doesn’t reach for my hand in the car anymore or when we are in public. She doesn’t want to shower with me anymore.

She doesn’t listen to what I say. It was earlier tonight when I picked her up from the Navy base and took her home with me so she didn’t spend Thanksgiving alone and I needed to stop at a gas station and I was mentioning the gas station from our trip to the mountains and she snapped at me and said “Can you get to the point?” Which really hurt my feelings and I told her “I don’t understand where the hostility is coming from” and she could tell I was really hurt by it and didn’t bother to apologize knowing she hurt my feelings, that has led me to believe she’s starting to lose feelings for me.
