Need a advice

Im 17 yo I met a guy 3 years older than me he left his number and we talked on fb after some time we met in person. The whole thing was kind of new to me considering I'm shy introvert that never had a bf.
Later on we met at his house And he kissed me, cheek for first. Then I eventually was feeeling it and we made out, it stayed that way but fingering and bj(from me but I was close for getting one before everything ended) got involved. Sex wasn't and option tho cuz I'm too young.
I didn't know what to think about it everything but I WANTED to like him and stuff like you know love and **** (I think I just liked him and I was accepting him). Sometimes I'd miss him but it wasn't really like he did too and he was intrested in other girls. We met not too often. So I thought it was kind of odd ( it was Wtf type of relationship but he wasnt clear about rulers or anything sooo overthinking is my nightmare).
I talked to my bff she told me to ask whether he cared about me etc. But I didn't get an answer? He was like ur asking black and white question and he told me that he couldnt take it seriously. Considering I was overthinking the whole relationship to the point of thinking he could be my bf BUT still thinking about how my future bf would be like I was like hm a mess.
When I told him that he doesn't give a damn about me he told my that that's my words... So after all I got angry and screenshoted everything to my bff (she helped me making texts too) and we joked. Eventually we wrote some hate comments about him under my photo then my bff wrote some under my photo on ig. He then wrote to me "thanks for excuse, I didn't offend anyone so bye." Later on we talked I somehow wrote a simple sorry (advice: it solves nothing lol) then again I was mean lol.
Then after a month I chilled with everything I suddenly thought that I could solve it differently? I mean as a person I avoid conflict and my reaction was influenced by my bff, I kind of cut the feelings from past toward him (just forgetting the bullshit you know everything got cleaner) and thought that what I did was egoistic and immature, obviously just rude. Like what have I done omg. So I tried to meet him but failed then he didn't have time, forgot so I ended up writing it although I wanted to do this face to face. But I think I was honest in it and it went well.
Then he wrote that if I was older Wtf he might consider just friends relationship. Then we talked a bit and he eventually wrote that "if you want to meet with me and get into action no talking you know where to find me otherwise don't take my time" and I was like okaaay why are you like nono then yes lol. I was like no way I'm having sex with him for sure. So I was like no. Then I thought about everything and I kind of missed the stuff (not like... him) and started considering asking whether we could get to what we did back then BUT with some rulers and obvsly no sex. But then no one would be able to know about this because I feel like my bff would kill me lol. But then id have to text him and ask about everything and stuff idk how he'd react too. And after what he wrote I texted that (about fwb stuff cuz I don't consider sex as an option but oral is fine for me actually)"youre overrating yourself and I agree with what you wrote" (about me being too young and stuff). I'm still thinking about it cause it's been just 3 days since that text. Now I keep my options open differently to what it was like before. And I don't know like yea It's not about morals tho! :p And it's legal in my country lol
