Opinions anyone?

So I met a guy roughly a month ago at my new job. I knew right away that he was not my type and didn’t want anything more than a friendship. I disclosed with him that since I’m starting my second year of college, I wasn’t looking for a serious, romantic relationship and I try really hard to not date my coworkers. I also have three jobs in total and go to school full time so even if I wanted a relationship I know I would never have the time. At the time I thought he understood my intentions on how I wanted the relationship to go. So a month passes and we hung out I few times outside of work (platonically) and today he texted me if I wanted to be his girlfriend and I respectfully declined but was still willing to continue the friendship if he desired. He seemed really distraught and acted as if I had been leading him on this entire time, which I feel like I have not since I told him in the beginning I was not interested.

I asked a few of my friends what their opinions were and they were all kind of the same “oh maybe he thought he could win you over” or “maybe you didn’t realize you were flirting back”. I told one friend that he told me he had never had a serious relationship and she said that maybe since he had never been in a serious relationship and that he’s almost 21 that he feels pressured from his friends and family to find a girlfriend. I feel like her explanation really stuck out because it honestly did feel like hanging out with a 16 year old boy sometimes (it just seemed like he had a noticeably high sex drive). He had asked a few times if I wanted to have sex and I respectfully declined because I still had no attraction to him. He also told me he was a virgin which I think is really hard for me to get past considering I lost mine almost 4 years ago. I feel as tho even if I was attracted to him that I still wouldn’t want to be the person he lost his virginity to. I never disclosed my thought about it to him.

I of course feel bad if he thought I felt anything romantic towards him but I told him at the beginning my opinions. I think it’s also difficult to believe he thought I liked him because I never intentionally flirt. I grew up with the majority of my friends being guys so it’s not hard for me to differentiate my attitude towards a relationship between a boyfriend and a guy friend.

It just kind of feels like I’m back in high school with the whole boy troubles and the fact that he texted me to ask if I wanted a relationship over asking me in person.

I was wondering if anyone else has had the same experiences in college or am I just putting too much thought into it? Or maybe if I was in the wrong what I could do to help avoid this in the future.

Thanks in advance!
