Am i wrong?

I had got pregnant and had both my babies out of wedlock, my daughter is almost 7 years old and my son is almost 8 months... 2 different bio dad's, I'm now with a wonderful man who treats my son as his own, he got with me while I was still pregnant with my son and he didn't care, he has no kids off his own and he he as stepped up so much by raising him as his own... We're think of getting married and having a child together one day... What does everyone think?
