I just read some of the emails here on being a step parent. I to, just became a step parent. I just recently got married. My husband as 2 kids. A boy 12 and a girl 16. His son is the same age as my son. My son doesn't live with me though. My husband has his son live with him. His son as lived with him for well over a year now. Apparently his mom ponded him onto his dad. I guess she couldn't handle him. It's awful when divorces causes a lot of ugliness for both sides when parents are trying to move on and forget what happened before. I just wished that we all would grow up and pay attention to what's really going on.  
Well, anyway when I came into my husband life, the beginning was good but then when my son came into the picture it was a little different. You see my son as a slight learning disability but I believe and hope he grows out of it. When my husband asked me to marry him after 2-3 months I was really surprised how things went. I accepted to marry him but after the marriage that's when things got kinda bad.  
He bought a house. Asked me if he should get the 3 or 4 bedrm and I said 3. I should've said 4 but a big difference on the prices gees on 3 to a 4 bdrm. His son was having problems dealing with his mom, dealing with his dad having me and my son around. I took so much from his son I had to leave. He started comparing me to his mom and his dad's ex girlfriends and then picked on my son because some of his dad's ex gfs had kids to and they picked on him so he thought he'd get my son. Finally dad put son in counseling to find out what's going on of why his son gets angry, mad and tempered so much. Found out his mom physically and mentally abused him in the past but I think his mom and dad apparently ruined him somehow. Mom went to his counseling but she doesn't remember what hppened back then. My husband said he had his son in counseling before but mom had it stopped but daughter said mom couldn't afford it but dad think it was because things were about to come out and mom stopped the counseling. I'm not with hubby now but we're trying to work things out but we'll see.
