Why do I feel bad?

So this guy and I talked for a month he never made any time for me he always had an excuse as to why we couldn't never hang out so I ask him of was even interested , he said he did like me but wasn't ready for a relationship, neither was I🤷‍♀️ but I was trying to get to know him first before we went to the next level long story short I just stop communicating with him I didn't see him for almost a month and now he comes around all the time cause he is best friends with my brother we say hello to each other but it's really awkward when we're around each other I don't why I feel bad.
