My first question is why on earth are you saddling yourself with someone else's child at the age of 18?? I get that you love this guy but you are WAY WAY WAY to young for this. Trust me, please really listen to this, LOVE IS NOT ENOUGH! It isn't, not when it comes to these blended families and all of the issues that come with them. I got married the first time at your age, I had my own son at 23. Young people getting married is hard enough, but adding step life to that- you are in for a very hard life, that in reality does not have to be.

I think the simple fact that its only been a year and you have that child who is only 2, you have a chance I think, just because he is young enough to where eventually he will look at you as a parent. Its much harder becoming a step mom when the kids are older. I started 12 years ago being a step parent to a 7 and 10 year old, they are adults now. at the time it was easier with the 7 year old then it was the 10 year old. I am wondering and hoping that with time, he will grow accustomed to you being in his life. A year may seem long since you are still young, but its not, trust me, when your my age (36) time flies faster then you would ever believe. Anyways give it more time. I know a part of me wants to say "Run" to you but you are married to him now and obviously in love with your husband. Just give it more time and more time may be another year. Just keep trying and letting him know you are there. He will come around. Also put your foot down though, don't let him keep you from your husband because the younger he learns that he is not in control the better off all of you are going to be.

Also how often do you have him? If its an every other weekend thing, that could be why it is taking him so long with you....if you have him full time or even half time, it will be quicker that he grows accustomed to you being there. In my opinion of course.
