but he told me all this stuff about he hasnt been loved before by a girl, and how i seem like the only nice person he has ever met
To me this was a red flag straight away. Sure, maybe that's true and he was being honest, but it really sounds like he's trying to guilt trip you to date him. The information he gave was just too heavy and too much in this stage of talking, and he must have known that it was going to make an kind hearted women to feel obligated.
I just feel bad though…he seems lonely and sad, and we just have a lot in common
Yes, because you are probably kind hearted. If you are religious, you will be aware of teachings about modesty or chastity, but what they don't teach young women enough is being modest about who you show kindness and patience to. so I want you to save this advice and keep it somewhere -
*It is not your job to save or nurture sad or damaged men, nor provide good fortune who've had back luck so far in life.
Your nurturing should be directed to a more appropriate place, like children, NOT adult men. If you want to give to others, then you can do so in a way that has safer and more appropriate boundaries, such as volunteering, becoming a therapist (where you could be paid for it), or helping out at an animal shelter*
On the dating side, I once changed my settings so that it appeared that I was in my mid 20s rather than mid 30s. I just wanted to see if it would make a difference since all I was getting was men far older than myself and my own age group was mostly missing.
And you know what? Once I did that, I saw soooo many men my own age or older that had mysteriously been missing when I was my true age. What was happening is that those men were either filtering out women in their age own group, and many were clearly lying, saying they were 28 when they clearly looked at least 35-40 years old.
Be careful. Sometimes we have to go through the discomfort of disappointing or upsetting someone in order to do what's right. And yes, I believe it's right to turn someone away if you don't find them sexually attractive, for one thing. A lack of attraction usually causes serious problems down the line.
