Should I pursue having a second child?

When I was 20 I had my first so with a former, close friend who allowed me to use his sperm though N.I to have a baby. I was and am finically stable, have my own double wide, with a decent amount of land, my own vehicle and a great job and I knew I wanted to have a child because I’ve never been the type of person to party I have alwayd been very family oriented but due to work I never had much of an opportunity to date or meet anyone. Now with a 1 and a half year old it’s basically impossible to date and as much as I’d like my children to have a father figure in their lives I don’t feel it’s 100% necessary. I really want my kids close in age and always have, so they can grow up together. I feel ready for a second child or like I will be by the time my son is two years old in June for sure, however I’m slightly conflicted because part of me really feels like if I put in time away from my son and work maybe I’ll find somone to settle down with. I’m only 22 now but waiting around for some “perfect guy” to accept me and more importantly my son just seems like something I could be waiting just to long for.
