Why do I keep looking at this guy's FB page ?

When we reject someone else, it's easy for us to move on.

When someone rejects US, it can make it difficult for us to move on - and it sounds like this is the case for you in this situation.

What is important is that you learn from your feelings, and then have the courage to move forward despite them.

You obviously still have feelings about him, and do need to move on. He is "single", but not interested in having a relationship with you. I suggest looking at the page one last time, and then pursuing other relationships and interests.

I'm sorry the relationship didn't work out, and that you are mourning the loss of what could have been - this is normal. However, this is an amazing opportunity for you to move forward and grow.

If you are unable to move forward after looking at the page one last time to say goodbye, then yes, you should seek professional help to discuss your feelings.

Best of luck to you!
