I've been dating with my girlfriend since I was 17. We are both 17. We have been together for 5 years. Just 2 years ago, we broke up as she felt she no longer feel any love for me anymore and our relationship was affecting her life as she was studying in college. But she still wants us to be friends. After a few months of being friends, I told her that I can't see her anymore as we are acting like couples but we were just friends. After a few days from not speaking to her, she decided that she want us to be back together as she really misses me a lot. From then on, we went back to how we were before. Now, I feel the same thing is happening again. She says she lost the spark in our relationship and it is getting boring. However, this time she does not want to break up and she wants us to work together to solve this problem. We are both in college and it's worrying me.

Can anyone advise me what I should do?

Sounds like she is growing away from you and she does not want to.
How old are you? You said you are 17 and have been dating this girl for 5 years.

I'm 22 this year. So I should be prepared for the worst?

I would say so. But this may be a good thing for both of you. You two may find out things about yourselves you never knew. Explore life as adults apart from each other.
