<human>: Can you give me a shortened version of the text?

So we've been dating for 3 months, things have been great. The first month and a half we dated we saw each other 3-4 times a week, watched movies, went on walks, etc. Our sex life was absolutely perfect. Last month she got a job, working nights, and with my school and work we're only able to see each other once a week: Sundays. It was alright for awhile, but now the last 2-3 weeks she's been texting and calling less and less, not initiating sex when I'm over (she usually does at some point) and when we are together all she does is talk about work and how horrible it is working so late, and how tired it makes her. When I ask her what's wrong, she just smiles and says that everything's great. I don't buy it. She smiles less, talks less, laughs less, doesn't say she loves me even when I tell her I love her. And I do, I love her to death. Up until a week or two ago we'd say it all the time, tell me how much she misses me, send me cute pictures on facebook, but now she's all but ignoring me. Practically refusing to go to a play I'm directing because it somehow interferes with her work (it doesn't). She's stressed and overwhelmed, and I get that, but I can't do much to help her, and when I can she won't let me.
<bot>: I think my girlfriend is losing interest in me, and I'm not sure what to do. I love her alot, and I need ways to revive our once amazing relationship
