Need some personal insights on having children-Do you plan on having children? (From psychology standpoint)?

Great Question. I'm 25 and me and my fiance both agreed on not having children. Growing up I had always been on thinking terms like that though. Growing up I was a very pretty girl, but had no interest in dating what so ever, so I didn't ever have a boyfriend. I found my fiance 5 years ago to be exact, such a short time to fall completely in love but it happened. I'm very self involved, and I am a very busy person. I think I am to self involved to care for a child the way a parent should, which isn't greedy of myself at all. I think children are for those who think they are blessings, because they really are. I like only having one significant other in my life I feel that children ruin marriages, or change them significantly, sometimes that is not the case though. (my point of view from being told by a relationship councelor ) Not having children is great for people like myself, very work & self involved.
