My girlfriend stopped having feelings for me
My girlfriend and I were together for 4 years, and were both very happy. She started talking to a guy at work, but stopped when she realised he only wanted her for sex. But in that time things between us became rough. She has started talking to him again and the relationship began to decline rapidly. She lied to me and I lost faith in her, and her granddad died so she said she couldn't deal with a relationship at that time. 2 weeks on she is writing to this guy saying she loves him and misses him and can't stop thinking about him (in a friends way) and she said she has stopped loving me. I have tried to put it back but no matter what I tried it didn't work. I paid for a holiday, but while we were there she spend all of the day at her sisters leaving me sat around bored. She said she doesn't know what she wants because she wants it to work but doesn't feel the same feelings for me as she did before. We have slowed things down but we still talk everyday and are best friends still. I want it to work and think that if we work at it we can bring those feelings back. What's the best way of going about things? I tried not texting her but it was far too difficult. I'm only 19 so she is the only girlfriend I have had, but I know she is all I want. I wanted to ask her to marry me when I got back from uni but wasn't given the time. What should I do?
