My long distance affair not working

I met Rachael who lives in Nairobi three years ago. I live in Nakuru and initially I thought I’d move closer to her with time, but this has proved difficult because I can’t get a job in Nairobi. We have been engaged for two years, but have not settled to get married yet. Of late, she appears to be losing interest in our relationship. She doesn’t call or reply to my messages as often as she used to, and she no longer responds positively to me. I am not sure of what she wants, but I know something is not right. Please advice ...
