The former glamour model was left devastated when she discovered her husband had cheated on her with two of her close friends, and though her first instinct was to end their marriage, she is not rushing into a decision.
In an interview with The Sun newspaper, Katie - who is pregnant with her fifth child, her second with Kieran - explained: ''I could throttle him but that doesn't mean I don't love him.
''When this happened I was straight onto my lawyer to get a divorce but I have taken a step back to give myself time to think. In a nutshell, I decided not to rip everything up without thinking everything through.
''I wanted to get through this period and have time to reflect. My life has been full of knee-jerk reactions and they've not always been the best things I've done.''
The 36-year-old beauty - who also has children Harvey, 12, Junior, nine, and Princess, seven, from previous relationships, and 11-month-old Jett with Kieran - insists her relationship with Kieran is far from back to normal.
She added: ''I haven't forgiven or forgotten, we are not sleeping in the same room or pretending all is fine. I'm going to help him get through his initial therapy, give birth and then we'll decide what's right for us.''
Katie also confirmed that her former stripper husband has been undergoing rehabilitation to treat his addiction to sex, which involved a four-day stint in rehab followed by an intensive 12-week therapy programme where participants must abstain from sex for its duration, and will wait until his treatment ends before making a decision about their future together.
She said: ''Kieran has been diagnosed with a compulsive sex addiction. It's like being a drug addict.
''The only reason I haven't kicked Kieran out is because I'm trying to understand why he's done this and the huge amount of effort he has put into his therapy.''
