Single or Committed! Which is best?

Over the last 10-15 years, I've seen many relationships and marriages fall apart. I'm an introvert and get scared to talk to girls, but I know what I want in a partner. Now my age is becoming a deciding factor, and I am unable to find the right person. Should I just drop the idea of finding a partner? I get many offers from married female friends to have an affair, but I always refuse as I believe in monogamous relationships. I have never dated anyone and don't know the consequences of getting into a relationship. I am old-fashioned and might faint if I touch a girl. I wrote poems about an imaginary girlfriend, but now this habit is boring. I tried expressing interest to a girl 7 years ago and failed miserably. I may have a complex because I am from a small village. I have traveled extensively and experienced a lot in life, but now I am not interested in food, travel, material things, women, or money. I bought properties and plan to sell them to remove loan burdens. Currently, I am back in my village, working from home and spending time on my farm, but even this is becoming boring. I am unable to bear the family pressure of marriage, as they will find someone from my village and force me to get married. My question is, why do women only fall for bad boys who eventually betray them? My worry is that even if I get into a wrong marriage, I will never betray my partner, but I fear the level of intimacy, affection, and emotional availability. I am thinking about how to force myself to deal with this.
