Questions: Relationships

I heard my boyfriend has a crush on another girl since the beginning of the school year in August. She recently joined his group for a class project so now they have each other’s numbers. I also heard my boyfriend would check her out a lot so I think he definitely has a crush and thinks she’s attractive

I know several guys like her so I’m kind of worried that he might go with her if she asks him even though he’s my boyfriend. What are the chances he would rather go with her?

I've personally known this guy for 5 months. I initiated conversation first and followed him first. We began texting each other and I ended up asking him out. Even though he agreed, he canceled on me twice. Despite him eventually telling me that he wasn't ready for a relationship and wanted to be friends, we still would text each other, a few times for hours til the early morning. He did admit to liking me and being attracted to me. One of the last things he texted me was, "although I was supposed to go to bed, know I'm thinking about you and I care about you".

A week later in person, I asked him, "How would you feel if you were to never see me again? How would you feel if we never spoke again?" His response was, "To be honest, I don't know how I would feel. I don't know". I just nodded my head and moved on. But what does this mean when a guy says this?

You just started talking, with no rapport & NO attempt by the other person to build a rapport. They pushed to meet quickly & when on the phone, for one, spoke of sex. You are NOT an easy person after cheap sex & told them this a few times but still NO attempt to build rapport.
