I found Him (Advice?)

Fourteen years ago the state took my children from me, they were 2 and four a boy and girl. My rights were terminated and the adoption of them was closed. I have known where they are all this time, but I waited until my son was 18 to try to contact them. I never wanted to loose them but I was homeless and stuff happened and they deemed it in their best interest for them to be given away. I fought very hard I just lost very bad. Not that it matters but I was never into drugs or anything it was just my lack of stability that cause what happened. I wrote my son a letter last December I never got a response so I thought maybe he wasn't interested in me? It hurt but I had decided to let him decide. I have always randomly googled my kids names in hopes of finding a blog or myspace or something of theirs to at least get a glimpse into their lives. Never had anything show up anytime I did it until last month. there was an article about my son, It was a court article saying that he was sentenced to prison. I checked out the prison and yes it is him and he will be there for a while. I wrote to him in the prison and told him who I am, he wrote me back and said he has always wanted to find me, that he still has a place in his heart for me, he is very sweet actually. He seems to express himself just like me, he looks like me too. He wants to keep in touch and i want to also. I'm thrilled actually, I'm so happy about this. But I hate that he is where he is. I forgive him of what he did. I love him anyway no matter what. But he says he loves me, is this possible? He doesn't remember me really. So It makes me wonder. Not that it would change anything if I found out he doesn't or couldn't love me, but I still just wonder if even tho he doesn't remember me that he could love me and not know me. The question doesn't stop me from giving him my love I love him so much I always have.
