I am not actually married but my boyfriend and I have lived together for 3 years so I am referring to his son as my stepson in this post. I usually don't call him my stepson but while searching for advice online it seemed that step-parenting help is what I need. He is 2.5 years old and I have been in the picture since day one. My boyfriend did not find out his ex was pregnant until we were already in a relationship (and lived together). I knew it wouldn't be easy but we were in love and I thought everything could work out ok. So I have been around since day one.
