I SAY YES!

Why?

You didn't say that you love her. After 4 years, you only 'really like' her.

Cut her loose.

I would have been gone a lot sooner as love is important.

Please don't backtrack now and say that you do love her....you stated "like" twice, and even if it was an oversight, your subconscious mind is saying that this isn't the passionate LOVE you are looking for.
