PLEASE - Serious responses only. I am almost 40 years old. I have been divorced twice. I enjoy....?

companionship.. Is there something wrong with the idea of getting married again and perhaps even having a child (I don't have any) Someone please explain to me why that is such a terrible thing. Don't people enjoy being in relationships? I enjoy having a best friend that is also my companion, my partner, someone to come home to, etc. Why do people run away at the first sign of commitment. I'm not asking for marriage on the first date or anything but why are people afraid of working towards that? Please don't make fun of me. I just enjoy companionship and don't want to spend the rest of my live being alone. Serious answers really appreciated. Thank you so much!
