I think I know why I'm lonely

Yesterday I seen an old friend that I had dated. We reconnected about a year ago but his conversation was bland and I was turned off by him not having his 'life' in order. He told me he was in barber school and had been laid off because of an ankle injury. Immediately a red flag went up that he was a slouch. So I never called him again and ignored his calls. Chatting with him yesterday I found out he was engaged and just had a baby. He is one of the most handsome men I've dated and I couldnt help but think, why did I let him go? The guy I dated last, Joe, sort of forced himself on me. He was too clingy and this really irritated me. He was recently divorced and living in an apartment behind his Pastors house, he had a decent job though and cut hair on the side. I tried talking to him about his clinginess but he seemed unmoved by it, and I always felt like he wanted to rush and live with me because he had no real place of his own, so I stopped calling him and eventually had to tell him I was over it. He also has moved on and been with the same girl for at least 6 months. Why are these men moving on to decent relationships but I'm still in the same space of loneliness? I havent been in a relationship in 2 years and after about 2-3 phone conversations I find something annoying about the guy. I talked to a male friend about this today and he told me I needed to grow up and give people a chance or I'll never have a relationship. He said I shoed men off like a teenage girl and no one is perfect. The talk today really helped me. I'm far from perfect, I dont have a career, I take care of my children solely on my own, i dont own a home, nor have I bought my first house, and my credit is eh...ify so for a man to accept me he'd have to accept flaws and all, I wasn't willing to do that. But now, I will go the extra mile instead of searching for a knight in shining armour, I will use patience and seek a man capable of being a knight :)
