What do you think about me being done with my fiance and am basically only still with him out of pity and laziness?
Is there a reason why you aren't breaking up with him?
He can be charming at times and I don't want to search for a new boyfriend
You are using your boyfriend if you stay with him just because you don't want to search for a new boyfriend. You are being unfair and a terrible girlfriend to him. Break up with him so that he has a chance to find someone who really loves him.
I've never loved him and it's going to end soon anyway.
If you believe it will end soon, then just end it now? Neither of you will be happy staying in a relationship for too long when you could have had something better.
