If I had to do it all over I wouldve never kissed you but at that time I just couldnt
Resists still can't believe you went and told her how well I got to know ya it's crazy baby I
Wasn't ready for this,

Breakin up is so hard to do babe, sometimes your feelings could get hurt and it seems like it
Wont work and im sorry I did not respect you babe why was I under her shirt liftin her skirt
What did I do baby shoulda known shoulda known that a man gets weak and I shoulda known shoulda
Known it could happen to me and im down on my knees begging please

For what it's worth I'll say im sorry but I know you wont forgive me so I had to put myself
Right in your shoes no matter how much you love me girl I did you so dirty and I see some you
Win and some you lose

Breakin up is so hard to do babe, sometimes your feelings could get hard and it seems like it
Wont work and im sorry I did not respect you babe why was I under her shirt liftin her skirt
What did I do baby I shoulda known shoulda known that a man gets weak [o baby] and shoulda know
Shoulda know it could happen to me sweet lady tell me what must I do baby, what I gotta do I
Made a fool outta myself and I feel so stupid baby and I really hate it I guess I should
Learned not to have taken time with someone else cause I'll end up losin my baby

I shoulda known shoulda known that a man gets weak and I shoulda known shoulda known it could
Happen to me

And this is what I shouldve done I shoulda known better I touched that stormy weather and it
Hit me right back in my face o baby I shoulda known better I touched that stormy weather and it
Hit me back in the face im all dismay
