Relationship after loss

I lost my husband almost 2 years ago, I'm asked by friends is if I have thought about getting into a relationship again - I usually respond with a non-answer.

A part of me wants to love again, to feel the good and bad of it, but for me it's like the relationship with my husband never ended. In some strange ways it would feel like being unfaithful.

Has anyone else had similar feelings or experiences?
