First Boyfriend?

To start I m 23 years old, due to a strict family, I was unable to get a boyfriend until now. A high school friend just asked me out yesterday. I accepted, he had asked me out in high school but at that time I rejected. I don t know if I still consider him a good friend or more, I was pressured by my sis as well as other outside sources to accept. I feel I probably should have waited to see if I could see him as more. At this point I don t know what I should do, he is the brother to another really good friend so even if I did break up with him now I don t want to lose her, because she is also friends with my only other friends and they will likely side with her and it will likely lead to my sis not seeing them either since she would disagree with me, but still side with me. Should I simply ride this out and see if anything comes of it? I likely would be able to break up with him but remain friends later on. Basically any advice works. Please no negative comments, you don t know me, don t assume things on your own.
