Sixties Song... Please Help!

I'm trying to identify this song from one of my Dads old mix tapes of 60s stuff so I can convert it to CD for Christmas. I've worked out the others but this has me stumped... please help!!

I gave my heart to you
The least that I could do
When you told me that your love
For me was really true.
I thought this love would be
Happiness for you and me
But I found out the hard way
You bring this misery

CHORUS:
Why did you break my heart running around?
Why'd you destroy all the joy that I found?
Why do you torment me when you know
That I never wanted to let you go?

Everytime that I see you
You're out with someone new
You don't know what I go through
Seeing someone else with you
I wish I could find a way
To bring you back someday
But I know that you'd always
Want to run away.

REPEAT CHORUS & VERSE 1.

Artist and title would be greatly appreciated!
Thanx

my little run around?

most of these answers can be found by just doing a google search, and putting the lyrics in quotations. (maybe 4 or 5 lines, not the whole song )
