confused feelings

Kirstie
I'm needing opinions on what I should do with my relationship..
I was with a guy for 2 years and 5 months but then we never saw each other because he was at work...
I met a guy and we were talking (as friends) I then made a stupid mistake of ending it with my boyfriend who I can now say meant so much to me..
I don't know if I should keep fighting to get him back of just move on with the new guy even though all I think about is my ex boyfriend? Thankyou
