My girlfriend of 2 says she needs space because of stress(Long distance relationship)

[Drewy1888]

I met my girlfriend about 2 years ago on the internet. We began dating about a month after we began meeting. She is about a 2 1/2 hour drive away and I see her on the weekends. I use to see her more often but she recently got a full time job. I am a full time college student so it has been hard to see eachother. Even though we see eachother on the weekends it feel like its not enough. I made a terrible mistake by telling her that it wasn't going to work out. After a day i felt like I made a terrible mistake. I felt so empty. I've been madly in love with her for a while now and it hurts that we are not togehter. I asked her if she wanted to work things out and she said she just wants to be friends right now. She said she is very stressed about her new job and all the pressure being put on her by her family and that she doesn't have time for a relationship right now. I think this breakdown may have had to do with me being upset because she goes out with her friends as soon as she gets home from work to relieve the stress. I don't mind if she goes out but it sucks when I can't talk to her before I go to sleep like I use to. She said things could change in the future. I told her I would give her space and time and that I just wanted the best for her. I love her so much that it is bothering me that there is a chance that she won't come back. What do I do? Any advice? This is my first long term relationship so I need all the tips I can get. Thank You.
