Trying something new

Im hoping this doesn't come off as one big ramble, but here it goes:So im a 35yr old gay male, Navy Veteran, who got out of a 5 year relationship about 6 month ago. I was determined to stay single for one year.... until this one person approached me and I couldn't resist. He's 22yrs old, Bi, good looking and very interesting. I enjoy his company and the time we spend together, however, I have many fears that bubble up.Im fighting very hard to not close myself off to the world as i know where that leads. I am not one to let my fears control me, but this time around I'm feeling especially cautions.These are my fears: Im 13 years older than him. I have not dated with this much of an age gap. Am i being stupid for even considering this? He is mature, its very evident and ill find out why soon enough, but am i being Naive? Wishful thinking?Im 35 yet i feel like I'm 80 because of the service; mentally. I notice that people gravitate to me because, I've been told, I'm "wise, comforting, easy to talk to and soothing." I am an empathic and caring person and a mentor to many. I enjoy helping others, being a good friend, and making people smile but as of my last relationship, I'm starting to feel that people date me for the qualities they see that i have, that they don't posses. Im starting to feel a bit used. Its as if they take until they are full, and then leave. Has anyone had a similar experience?I dunno. I just feel like i am getting older and i see my friends pairing up and getting married and here i am. Im happy chasing my dreams, focusing on school, my career, my dog, family and friends, but it would be nice to have something that lasts longer than my record setting 5 years.Feedback is much appreciated from someone who feels a bit lost in regards to the dating world.
