<human>: Summarize the given text in a few sentences.

We've been together for around 2 years and overall it's been a really good relationship.  

Lately he's been blowing off plans with me to hang out (drink) with his guy friends. I don't mind him hanging out with them more, but I don't see why he always has to do it when he's already committed to hanging out with me.  He never used to do this before.  
  
Does this mean he's losing interest in me? Or maybe he's getting too comfortable and thinks blowing me off is okay? I've tried talking to him about it and he is really stubborn and thinks it's not a big deal. Or he backtracks and says he never really committed to the plans with me. We've been really happy for a long time and I know he's not cheating on me. What should I do?
<bot>: Boyfriend keeps ditching me to hang out with his friends when we've already made plans and I don't know what to do.
