What makes some men mature or immature, and what makes some immature or mature is their personality traits?

A guy my age was 33 years old and I gave up, so I checked an online dating site called freedating. co. uk and saw a guy who was different. It was me who messing with him first, and in response he sent me a message and asked to talk on Whatsapp. On freedating. co. uk, other profiles listed Casual Relationships, Serious Relationships, and Friendships. Other guys just listed Casual Relationships on their profiles and others said friendship. A new man was 31 years old. That I have been communicating with on WhatsApp and whose profile says he has autism and ADHD stands out from the rest. my traits in men that i like are respectful honest about what they looking for or interested in, open minded, communication , trustworthy, ask questions if you don't know and common interested. The first guy was all over places with different women but still was in a relationship i saw on Facebook. The first guy was no good and was a player and a cheater that i only found out through facebook. One woman commented that she had been in a relationship for four years with the first guy and i did move on to the new men that i been messaging on whatapps and setup a meetup/first date at public parks. the new men did let me know he was seeing a girl but the girl broke off because she said he was going to slow and he didn't had to messaging me that but he did anyway. When it comes to men, maturity or immaturity depends on their personality traits, not their age?
