<human>: We have been dating for 4 years and living together for over 1 year. I still love her very much regardless of the next couple concerns. I just think she is in a bit of a funk or something. So I have a couple mixed feelings:

1. She doesn't go out of her way to express love or many other emotions toward me anymore. It's like we are roommates, not partners. It's been going on since the beginning of 2016 or late 2015. I think she is stressed out from school. But I have a lot going on too and I am still caring/happy around her. Recently when I got a cold, she asked me to stay in a hotel because she didn't want to catch it. I understand not wanting to get sick. But when she gets sick I make sure she is comfortable, I buy her medicine, I take care of all the chores, etc. She doesn't do any of that stuff for me. Or when I make advances for sex or even just ask if she wants to have sex, I am almost guaranteed to get shutdown. We've had sex once in the last three months. She said she feels fat but I told her i love her body. What else can I do to help her get in the mood?

2. I really want kids (not now but in the next 10 years) and she doesn't want kids ever. This is my biggest concern because it stops me from thinking too far in the future with her. Is it right to end a good relationship because I want kids and she doesn't? Especially since I don't want them immediately. 

How should I address these concerns? Our lease for our apartment is up in august, so I'd like to address the concerns before we sign another 12 month lease.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Girlfriend doesn't reciprocate love like she used to and we rarely have sex. She also doesn't want kids and I do want kids in the next 10 years. How do I address these concerns?
