im stuck

my 3 year relationship has come to somewhat of an end yet we both still want things to work out. we've been talking alot.

when we had first initial broken up I had met a guy and we hit it off.

I definitely do not want to lose either but I know I will have to. I just don't know what to do. do I go with what I've known and loved for 3 years despite all the hurt and bullshit we went through? or do I start all over with someone with a clean slate?....
