Age Difference

Please bare with me as I’m on month 4 of recovering a really bad head injury and I feel like now what I say gets taken wrong. This year has been a really rough year dating wise. I went through three guys my age or a little older that all freaked out on me. The first had some traumatic things happen, he became on and off after that and when he realized in one of his disappearances I was seeing someone else and wasn’t willing to cut things off flipped on me right after my grandpa passed away and said I was just sex. The one that I had started seeing I liked and was a little older. Him 30 me 26. I thought he would be a little more mature but I was wrong. We still play around from time to time but we’ve both come to understand it will never be more. I then met my dream guy (my age) but when I couldn’t do much since it was after injury on top of my schedule kept changing with work he thought I was avoiding him and blocked me. Now here I am and there is a really sweet guy that hasn’t given up on trying to ask me out since he started working for my workplace. He’s always asking me to do stuff and bringing me food and trying to make me smile. He’s overall a complete gentleman from what I can tell. He’s fairly close to my type a little shorter than I prefer but his sweetness had me looking past it. Here is where I’m hung up. While we are not technically co workers I still can’t shit where I eat. I also have to take his ID everyday and I recently noticed he’s just turned 21 a couple of days ago. Five almost 6 years difference seems like a lot with him barely legal and I’ve never dated more than 2 years younger after doing that in High school and beginning of college. I always dated older after all the way up till this year trying my age. My longest relationship being with someone 2 years older than me. At what age do y’all feel like it doesn’t matter anymore and does it matter more when the guy is younger? I always thought guys would be more mature if I dated older but I’ve learned age is just a number. Just for reference my parents are about the same age gap and my dad only stuck around for me and my brother as they just aren’t a good match. I also have a female friend my age who is dating a 40 year old and it’s the most pure relationship I’ve seen. Like I said please bare with me as I’m not sure this will be taken as intended.
