CONFUSED; My Husband Cheated, Do I Cheat Too, To Feel Better?

This message was sent to us via email by one of our good reader, who needs your advice on what to do about her cheating husband, she sincerely needs your advice as if you were given it to your own sister;

Dear Readers,

 I have been married for a year and 9 months  now. I am a 28 year old woman(name with held). My husband and I decided not to have kids until after two years of marriage, to enable us enjoy the home before the kids come. Sometime last month, My husband was taking a shower after work. His phone rang and I decided to take the call for him. That is not wrong because we take each others call. My husband stored this number as Seyi. I quickly took the call and what I heard shocked me. More after the break

Baby, I have been trying to call you, why didn’t you pick my calls on time? Are you home yet?

I was stunned, just a year and a half into marriage and my hubby was already cheating on me? I answered the lady and told her, I was Tunde’s wife and she quickly dropped the call. When he came out of the bathroom, I confronted him and he didn’t deny. He asked me to forgive him, that it was the devil’s handwork, that it will not repeat itself again. I feel hurt and in pain. Why did he cheat on me? What will happen when we have kids. Should I cheat on him, so i don’t feel hurt when he does the same? Please I need your sincere opinion and advice on this ..

Thanks.
